Solvent Red 43

What is Solvent Red 43?

Solvent Red 43 is a synthetic organic dye classified as an anthraquinone derivative, known for its vibrant red color and excellent solubility in non-polar solvents. It is primarily used in industrial applications, including the coloration of fuels, oils, waxes, and plastics. The dye exhibits strong thermal stability, making it suitable for high-temperature processes. While not commonly used in biological or food-related applications due to its synthetic nature, it plays a significant role in manufacturing and automotive industries, particularly in marking and dyeing hydrocarbon-based products.

What is Solvent Red 43 used for?

Solvent Red 43 is primarily employed as a colorant in non-aqueous applications, particularly in fuels, oils, and industrial solvents. This synthetic anthraquinone dye provides a stable red coloration in hydrocarbon-based products, making it valuable for marking and identifying different fuel grades. The dye is commonly used in aviation gasoline (avgas) to distinguish between fuel types and ensure proper usage. Its excellent solubility in organic solvents and resistance to fading under extreme conditions make it ideal for automotive and aerospace applications. Additionally, Solvent Red 43 finds use in plastics, waxes, and lubricants where permanent, heat-stable coloration is required. The dye's chemical stability ensures long-lasting color integrity even in harsh industrial environments.

What is the feature of Solvent Red 43?

Solvent Red 43 is characterized by its intense red coloration, high solubility in organic solvents, and resistance to heat and light degradation. As an anthraquinone dye, it provides excellent chemical stability, making it ideal for long-lasting applications in fuels, oils, and plastics. Unlike water-soluble dyes, it thrives in hydrophobic environments, ensuring consistent performance in industrial settings. However, due to its synthetic composition, it is not suitable for food, cosmetics, or biomedical uses. Its primary advantage lies in its durability and vivid color retention under extreme conditions.
