34dichloroaniline

34dichloroaniline, also known as 3,4-dichloroaniline, is an organic compound belonging to the class of aromatic amines. Its chemical structure consists of a benzene ring with two chlorine atoms attached at the meta and para positions relative to an amino group (NH₂). The compound has the molecular formula C₆H₆Cl₂N and a molar mass of approximately 162.02 g/mol.

3,4-dichloroaniline is typically produced through the chlorination of aniline or other aromatic amines under controlled conditions. It is a white to off-white crystalline solid that is soluble in organic solvents but sparingly soluble in water. The compound exhibits a characteristic amine odor and is sensitive to light and air, which can lead to oxidation and discoloration over time.

Due to its chemical structure, 3,4-dichloroaniline is primarily used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and dyes. It plays a role in the production of certain fungicides, herbicides, and rubber chemicals. The compound’s reactivity allows it to undergo further transformations, such as acylation, sulfonation, or nitration, to form more complex derivatives.

From a safety perspective, 3,4-dichloroaniline is considered hazardous. It may pose risks to human health through inhalation, ingestion, or skin contact, as it can be toxic and potentially carcinogenic. Proper handling, including the use of protective equipment and ventilation, is essential when working with this compound. Environmental regulations often classify it as a pollutant due to its persistence and potential bioaccumulation in ecosystems.

Storage should be conducted in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers. In case of accidental exposure, medical advice should be sought immediately, and appropriate first aid measures should be followed.
