CAS 1934-20-9

C.I. Acid Orange 12

Description:

C.I. Acid Orange 12, with the CAS number 1934-20-9, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This dye is characterized by its vibrant orange color, which results from the presence of azo groups (-N=N-) in its molecular structure. Acid Orange 12 is soluble in water, making it suitable for use in aqueous dyeing processes. It exhibits good lightfastness and stability under acidic conditions, which is advantageous for its application in acidic dyeing environments. However, like many azo dyes, it may raise environmental and health concerns due to potential degradation products that can be harmful. Therefore, its use is often regulated, and safety assessments are necessary to ensure compliance with health and environmental standards. Overall, C.I. Acid Orange 12 is valued for its coloring properties but requires careful handling and consideration of its environmental impact.
