CAS 119-93-7: o-Tolidine
Description:o-Tolidine, also known as 3,3'-dimethylbenzidine, is an organic compound with the chemical formula C14H16N2. It is characterized by its structure, which features two amino groups attached to a biphenyl framework, specifically at the ortho positions relative to each other. This compound appears as a yellow to orange crystalline solid and is soluble in organic solvents but has limited solubility in water. o-Tolidine is primarily used in the production of dyes and pigments, particularly in the textile and paper industries. However, it is important to note that o-tolidine is considered hazardous; it is a potential carcinogen and can pose health risks upon exposure. Safety precautions are essential when handling this substance, including the use of personal protective equipment and proper ventilation. Additionally, due to its toxicological profile, o-tolidine is subject to regulatory controls in many regions, emphasizing the need for careful management in industrial applications.
