CAS 6373-74-6

C.I. Acid Orange 3

Description:

C.I. Acid Orange 3, with the CAS number 6373-74-6, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This compound is characterized by its vibrant orange color, which results from the presence of azo functional groups (-N=N-). It is water-soluble, allowing it to be easily incorporated into aqueous solutions for dyeing processes. The dye exhibits good lightfastness and stability under acidic conditions, making it suitable for use in environments where pH may vary. However, like many azo dyes, it may pose environmental and health concerns, as some azo compounds can release aromatic amines upon degradation, which are potentially carcinogenic. Therefore, its use is regulated in many regions. In terms of chemical structure, Acid Orange 3 typically features sulfonic acid groups that enhance its solubility and affinity for various substrates. Overall, while it is a versatile dye, considerations regarding safety and environmental impact are essential in its application.

Acid Orange 3

CAS: 6373-74-6

Acid Orange 3 is a cationic surfactant that belongs to the family of dyes. It is used as a granulosa cell stain in histology, with the basic structure of a monosodium salt. Acid Orange 3 exhibits chronic oral toxicity in rats and mice, but does not show liver lesions at doses up to 4000 mg/kg. It has been shown to cause increased incidence of fatty acid oxidation, carcinogenic potential, and carcinogenesis studies in rats. Acid Orange 3 may also cause allergic reactions, such as skin irritation and erythema when applied topically. In some cases, it has been reported to cause contact dermatitis.
