Basic Green 4 CAS 2437298 Suppliers and Factory in China
Basic Green 4, scientifically recognized as Malachite Green, is a high-performance synthetic triphenylmethane dye characterized by its intense, vibrant green hue. As a cationic (basic) dye with positively charged nitrogen groups, it exhibits exceptional solubility in water and various alcohols, making it a versatile agent for both industrial coloration and biological applications. Its unique chemical structure enables strong binding to proteins and nucleic acids, ensuring superior adherence to diverse substrates.
Beyond its role as a coloring agent, Basic Green 4 is highly valued for its potent broad-spectrum antimicrobial and antifungal properties. It is widely employed in specialized fields such as aquaculture for treating parasitic infections and in histology as a critical biological stain for microscopic cellular analysis. From textile dyeing of silk and leather to precision analytical chemistry as a redox indicator, Basic Green 4 delivers consistent and reliable performance across multiple high-demand industrial sectors.
