Technical Definition and Chemical Properties
Technically, Solvent Red 23 is defined as 1-[(4-(Phenylazo)phenyl]azo]-2-naphthol, featuring a molecular formula of C22H16N4O and a molecular weight of 352.40. It is categorized as a solvent dye, meaning it is completely insoluble in water but highly soluble in organic media including chloroform, ethanol, and petroleum ether. This unique solubility profile is what makes cas no 28348 53 0 ideal for non-polar applications.
From a physical standpoint, the material appears as a brown-red powder with a melting point ranging between 196-208℃. This high melting point is a key indicator of its thermal stability. Furthermore, it meets strict purity standards, with sulfated ash limited to 0.1% max and loss on drying kept under 0.5% max, ensuring that the performance of cas no 28348 53 0 remains consistent across different batches.
Beyond its use as a colorant, the product is highly valued as a biological dyeing agent. Its ability to pass biological stain tests confirms its utility in laboratory settings where precise cellular or tissue marking is required. The chemical inertness of the anthraquinone structure ensures that it does not interfere with the structural integrity of the materials it dyes, maintaining the purity of the result.
Key Performance Factors of cas no 28348 53 0
The efficacy of cas no 28348 53 0 is determined by several core factors: solubility, tinting strength, and lightfastness. Solubility in hydrocarbons allows for an even distribution of color in fuels and waxes without the need for expensive emulsifiers. High tinting strength means a lower concentration of dye is needed to achieve a deep red color, which is essential for maintaining the physical properties of the host material.
Additionally, its resistance to UV exposure prevents fading, which is a common failure point for lower-grade solvent dyes. This makes it highly reliable for outdoor industrial coatings and markers that are exposed to sunlight for extended periods. The combination of these factors provides a scalable and cost-efficient solution for high-volume industrial production.

Real-World Industrial Applications
In the energy sector, cas no 28348 53 0 is widely utilized for the marking of fuels and lubricants. Because it is oil-soluble, it ensures a perfectly homogeneous mixture, which is vital for preventing sediment buildup in fuel lines while providing a clear visual indicator of fuel grade or origin. This application is critical in preventing fuel fraud and ensuring the correct distribution of industrial-grade oils.
The plastics and packaging industry also relies heavily on this dye for tinting polystyrene and PVC. Due to its resistance to migration, the bright red hue remains locked within the polymer matrix, preventing the color from transferring to other surfaces. This is particularly important in the manufacturing of specialty coatings and printing inks for packaging, where visual precision and durability are paramount.
Long-Term Value and Advantages
The long-term value of utilizing high-purity cas no 28348 53 0 lies in its reliability and efficiency. By reducing the amount of dye required to reach the target shade, companies can lower their raw material overhead without sacrificing quality. Moreover, the stability of the dye means that end-products have a longer shelf life and a slower rate of degradation, enhancing the brand trust of the final manufacturer.
From a technical standpoint, the chemical inertness of Solvent Red 23 provides a safety margin during the mixing process. It does not react unpredictably with most synthetic polymers, reducing the risk of batch failure or product contamination. This reliability translates into higher production yields and fewer waste materials, aligning with modern industrial goals of lean manufacturing.
Furthermore, its utility as a biological dyeing agent adds a layer of versatility. Laboratories can rely on the same high-standard chemical for sensitive staining processes, knowing that the purity levels (such as the low sulfated ash content) will not interfere with biological observations. This multi-sector utility makes it a strategic asset for chemical distributors and researchers alike.
Future Trends in Solvent Dye Innovation
As the industry moves toward "Green Chemistry," the focus for cas no 28348 53 0 is shifting toward more sustainable production methods. Research is currently being conducted to reduce the environmental persistence of synthetic dyes by improving the efficiency of the synthesis process and developing better waste-treatment protocols for the anthraquinone residues.
Digital transformation is also playing a role in how these dyes are applied. With the rise of automated dosing systems in fuel and plastic plants, there is a growing need for dyes with extremely tight specification tolerances. This ensures that automated systems can maintain perfect color consistency without manual adjustment, further increasing the demand for high-purity batches.
Additionally, the integration of solvent dyes into smart materials—such as color-changing indicators for lubricant degradation—represents a frontier of innovation. By leveraging the stability of cas no 28348 53 0, researchers are looking for ways to create functional dyes that provide not just color, but diagnostic information about the state of the material they are in.

FAQS
Solvent Red 23 is highly valued for fuel marking because of its absolute insolubility in water and superior solubility in non-polar hydrocarbons. This prevents the dye from separating or forming precipitates in the fuel tank, ensuring a consistent color throughout the batch. Additionally, its high tinting strength means only a tiny amount is needed to clearly identify the fuel grade, making it cost-effective for large-scale operations.
No, Solvent Red 23 is strictly intended for industrial and technical applications. Due to its synthetic nature and potential toxicity concerns, its use is restricted in food-contact materials and cosmetics. It is ideal for technical plastics like PVC and polystyrene that are not intended for direct food contact, as well as for automotive and industrial coatings.
Plastic extrusion and injection molding often occur at very high temperatures. With a melting point between 196-208℃, Solvent Red 23 can withstand these thermal stresses without decomposing or shifting in color. This ensures that the final plastic part maintains a vibrant, uniform red hue without the "burnt" spots or fading associated with lower-quality organic dyes.
Yes, one of the key applications of Solvent Red 23 is as a biological dyeing agent. It passes rigorous biological stain tests, making it suitable for highlighting specific structures in tissues or cells. Its high purity, characterized by very low sulfated ash and moisture content, ensures that the staining process is precise and does not introduce unwanted chemical artifacts into the sample.
The primary difference is solubility. Water-soluble dyes are designed for textiles and papers, whereas solvent dyes, like Solvent Red 23, are designed for non-polar substrates like oils, waxes, and plastics. Solvent dyes do not dissolve in water, which prevents them from leaching out of the material when exposed to moisture, providing much better durability and "bleed" resistance in industrial environments.
To maintain the purity and effectiveness of the powder, it should be stored in a cool, dry, and well-ventilated area, away from strong oxidizing agents. It is typically packed in 25kg fiber drums to protect it from moisture and light. Keeping the containers tightly sealed prevents the 0.5% max loss on drying limit from being exceeded, ensuring the dye remains free-flowing and easy to mix.
Conclusion
Solvent Red 23 stands as a cornerstone in the world of industrial colorants, offering an unparalleled combination of thermal stability, organic solubility, and tinting strength. From its critical role in fuel marking and plastic coloration to its specialized use as a biological stain, the technical properties associated with cas no 28348 53 0 provide manufacturers with a reliable tool for achieving precise visual results in challenging non-polar environments.
Looking forward, the continued evolution of solvent dyes will likely focus on enhancing environmental sustainability and integrating with automated industrial systems. For companies seeking to optimize their production quality and ensure long-term color permanence, investing in high-purity synthetic dyes is not just a technical choice, but a strategic advantage.
