1,3-Naphthalenedisulfonic acid, 8-[2-[3,3′-dimethoxy-4′-[2-[4-[[(4-methylphenyl)sulfonyl]oxy]phenyl]diazenyl][1,1′-biphenyl]-4-yl]diazenyl]-7-hydroxy-, sodium salt (1:2)

Description:

1,3-Naphthalenedisulfonic acid, 8-[2-[3,3′-dimethoxy-4′-[2-[4-[[(4-methylphenyl)sulfonyl]oxy]phenyl]diazenyl][1,1′-biphenyl]-4-yl]diazenyl]-7-hydroxy-, sodium salt (1:2), with CAS number 6548-30-7, is a complex organic compound characterized by its sulfonic acid groups and azo dye functionality. This substance typically exhibits high solubility in water due to the presence of sodium salt and sulfonate groups, making it useful in various applications, including dyeing and as a pH indicator. The presence of multiple aromatic rings contributes to its stability and potential for colorimetric properties. Additionally, the compound's structure includes methoxy and hydroxy substituents, which can influence its reactivity and interaction with other chemical species. As an azo compound, it may also exhibit vivid colors, which are characteristic of many azo dyes. Safety and handling precautions should be observed, as with many organic compounds, particularly those with sulfonic and azo functionalities, due to potential toxicity and environmental impact.

Acid red 128

CAS: 6548-30-7

Acid Red 128 is a red dye that is used as a food colorant and as a pharmaceutical drug. Acid Red 128 is used in the diagnosis of bacterial strains, viruses, and human proteins. It has been shown to have antiviral activity against influenza virus and HIV. The hydroxyl group on the molecule reacts with the amino group of an amino acid or protein to form an ester bond, which links two molecules together. This reaction product is called a cross-link. Acid Red 128 can also be used as a growth factor by increasing cellular protein synthesis.
