2aminotoluene

2-aminotoluene, also known as ortho-toluidine or o-toluidine, is an organic compound with the chemical formula C7H9N. It is an aniline derivative where a methyl group is attached to the benzene ring at the ortho position relative to the amino group. It is a colorless to pale yellow liquid with a characteristic amine odor.

2-aminotoluene is primarily used as an intermediate in the synthesis of various chemicals, including dyes, pigments, pesticides, and pharmaceuticals. It is a key building block for azo dyes, which are widely used in textiles, printing inks, and food coloring. In the agricultural sector, it is employed in the production of certain herbicides and insecticides. It also finds application in the manufacturing of rubber chemicals and as a laboratory reagent.

The production of 2-aminotoluene typically involves the reduction of 2-nitrotoluene. Common reducing agents include iron and acid, or catalytic hydrogenation. It is important to handle 2-aminotoluene with care as it is considered a toxic substance and a suspected human carcinogen. Exposure can occur through inhalation, skin absorption, or ingestion, and appropriate safety precautions, such as ventilation and personal protective equipment, should be employed.
