24Dichlorophenylamine

2,4-Dichlorophenylamine, also known as 2,4-dichloroaniline, is an organic compound with the chemical formula C6H5Cl2N. It is a derivative of aniline where two chlorine atoms are substituted at the ortho (2) and para (4) positions of the phenyl ring. At room temperature, it typically appears as a crystalline solid, often white or off-white in color.

This compound is an important intermediate in the synthesis of various chemicals, including dyes, pigments, and pesticides. Its reactivity stems from the amino group and the presence of the electron-withdrawing chlorine atoms on the aromatic ring. It can undergo reactions such as diazotization and coupling, which are fundamental in dye chemistry.

2,4-Dichlorophenylamine is generally synthesized through the reduction of 2,4-dichloronitrobenzene. Exposure to this chemical can pose health risks, and appropriate safety precautions should be taken during its handling and use. It is classified as a hazardous substance, and its environmental impact is also a consideration in its industrial applications. Due to its use in pesticide manufacturing, it can be found as a degradation product of certain agricultural chemicals.
