34Dichlorophenylamine

3,4-Dichlorophenylamine, also known as 3,4-dichloroaniline or DCA, is an organic compound with the chemical formula C6H5Cl2N. It is an aniline derivative where two chlorine atoms are substituted onto the phenyl ring at the 3 and 4 positions. At room temperature, it is a solid, typically appearing as white to light brown crystals.

This compound is primarily used as an intermediate in the synthesis of various organic chemicals, including pesticides, dyes, and pharmaceuticals. Its chemical structure makes it reactive and suitable for further chemical modifications. For instance, it is a precursor in the production of certain herbicides and fungicides.

3,4-Dichlorophenylamine is characterized by its relatively low water solubility but good solubility in organic solvents. Its physical properties, such as melting point and boiling point, are well-documented in chemical literature. The compound's toxicity and environmental impact are subjects of scientific study, and appropriate safety precautions are necessary when handling it due to potential health hazards. Regulatory guidelines often govern its production, use, and disposal to minimize risks to human health and the environment.
