Description

Sudan I is a synthetic organic azo compound widely utilized as a colorant in various industrial applications. Its primary value lies in providing a stable and vivid orange-red hue to non-food materials, making it a critical component for manufacturers requiring consistent coloration. This product is essential for industries involved in the production of plastics, waxes, polishes, and other specialty chemicals where color fidelity is paramount. We supply high-purity Sudan I CAS NO 842-07-9 to meet the stringent quality demands of global industrial markets.

Application

• Coloration of hydrocarbon-based industrial products such as waxes, polishes, and lubricants.
• Pigment for plastics and synthetic polymers to achieve specific orange-red shades.
• Staining agent in laboratory and microscopy for biological and material science research.
• Colorant for inks and dyes used in non-food contact applications.
• Intermediate in the synthesis of more complex azo dyes and pigments.
• Coloring agent for solvents and fuel markers for identification purposes.
