PRODUCT USAGE
Solvent Red 24, also known as Sudan IV, is a versatile oil-soluble azo dye valued for its intense red brightness and excellent solubility in non-polar environments. In the petroleum industry, it is a critical diagnostic tool used to color-code fuels, lubricants, and heating oils for grade identification and tax compliance (such as "red diesel"). Its exceptional thermal stability and compatibility make it a preferred choice in the plastics industry for the transparent coloration of thermoplastic resins like PS, ABS, and PMMA. Additionally, it is widely employed in the wax and coating sectors for manufacturing colored candles, shoe polishes, and solvent-based printing inks. In biomedical research, it serves as a specialized biological stain for identifying lipids and triglycerides in tissue sections.
