Orthotoluidine

Orthotoluidine, also known as 2-methylaniline or o-toluidine, is an organic compound with the chemical formula C7H9N. It is an aromatic amine and a derivative of aniline, with a methyl group attached to the ortho position of the benzene ring. Orthotoluidine is a colorless liquid at room temperature, though it can darken to a yellow or brown hue upon exposure to air and light. It has a characteristic odor, often described as amine-like.

This compound is primarily used as an intermediate in the synthesis of various chemicals, including dyes, pigments, and rubber accelerators. It is also employed in the production of certain pesticides and pharmaceuticals. In the realm of dyes, orthotoluidine is a precursor to azo dyes, which are widely used in textiles and printing.

Orthotoluidine is flammable and should be handled with care. It is classified as a hazardous substance, and exposure can occur through inhalation, skin absorption, or ingestion. Health effects associated with orthotoluidine exposure can include irritation to the skin, eyes, and respiratory tract. Long-term or significant exposure has been linked to more serious health concerns, including a potential for carcinogenicity. Due to these risks, strict safety protocols are necessary when working with this chemical, and its use and disposal are subject to regulatory guidelines in many countries.
