1-[2-(2-Methylphenyl)diazenyl]-2-naphthalenamine

Description:

1-[2-(2-Methylphenyl)diazenyl]-2-naphthalenamine, with the CAS number 131-79-3, is an organic compound characterized by its azo structure, which features a diazo functional group (-N=N-) linking two aromatic systems. This compound typically appears as a solid and is known for its vibrant color, often associated with azo dyes. It exhibits good solubility in organic solvents, making it useful in various applications, including dyeing and pigment formulations. The presence of both naphthalene and substituted phenyl groups contributes to its stability and potential reactivity, particularly in electrophilic aromatic substitution reactions. Additionally, due to its azo linkage, it may undergo reduction to form amines, which can further participate in chemical reactions. Safety considerations are important, as many azo compounds can be toxic or carcinogenic, necessitating careful handling and disposal. Overall, this compound is significant in the field of organic chemistry and materials science, particularly in the development of dyes and pigments.

o-Tolueneazo-2-naphthylamine

CAS: 131-79-3

Tolueneazosulfonamide is a derivative of tolueneazo-2-naphthylamine. It is used as a diagnostic agent for c. glabrata, which is also known as piedra or calcific band keratopathy. Tolueneazosulfonamide has been shown to have a thermal expansion coefficient similar to that of the eye lens, and this may be the reason for its use in the diagnosis of piedra. It has been shown to cause cell death by inhibiting host protein synthesis. This drug also has an inhibitory effect on some oral pathogens and can be used for the treatment of ocular infections caused by these bacteria.
