CAS 6375-55-9

Acid yellow 42

Description:

Acid Yellow 42, with the CAS number 6375-55-9, is an organic dye belonging to the azo dye class, characterized by its vibrant yellow color. It is primarily used in various applications, including textiles, paper, and food products, due to its excellent coloring properties. The dye is water-soluble, which enhances its applicability in aqueous solutions. Acid Yellow 42 is known for its stability under normal conditions, although it may be sensitive to light and heat, which can affect its colorfastness. As an azo compound, it contains one or more azo groups (-N=N-), which are responsible for its color. While it is widely used, there are concerns regarding the potential toxicity and environmental impact of azo dyes, particularly regarding their breakdown products. Therefore, regulatory measures may apply to its use in certain applications, especially in food and cosmetics. Proper handling and disposal practices are essential to mitigate any associated risks.

C.I.Acid Yellow 42

CAS: 6375-55-9

C.I.Acid Yellow 42 is a reactive dye that belongs to the class of chromatic compounds. It is used in photolithography and as a pH indicator, but is also an environmental pollutant. C.I.Acid Yellow 42 is hydrated and has radical mechanism of photodecomposition, which makes it subject to radiation and mineralization. C.I.Acid Yellow 42 can be used in assays for detecting ions such as copper, iron, zinc, or mercury at efficiencies greater than other dyes in the same class. It can also be synthesized from organic materials or biodegradable substances such as dyes from natural sources or phenol-formaldehyde resins with low toxicity to humans and the environment.>>END>>
