3,3′-Dichlorobenzidine

Description:
3,3′-Dichlorobenzidine, with the CAS number 91-94-1, is an organic compound that belongs to the class of aromatic amines. It is characterized by the presence of two amino groups (-NH2) attached to a benzene ring that is substituted with two chlorine atoms at the 3 and 3' positions. This compound typically appears as a solid, often in the form of a yellow to brown powder. It is known for its use in the production of dyes and pigments, particularly in the textile industry. However, 3,3′-Dichlorobenzidine is also recognized for its potential health hazards, as it is classified as a probable human carcinogen. Its handling requires strict safety measures to minimize exposure, as it can be absorbed through the skin and may pose environmental risks. The compound is soluble in organic solvents but has limited solubility in water. Due to its toxicological profile, regulatory measures are in place to control its use and disposal.
