Methylaniline

Methylaniline is an organic compound with the chemical formula C₇H₉N. It is a derivative of aniline, consisting of an amino group attached to a methyl group. Methylaniline is used as a precursor for the synthesis of many chemicals, including dyes, pharmaceuticals, and polymers.

Structure and properties

Methylaniline is a colorless liquid, although it can appear yellow due to impurities. It has a strong, unpleasant odor. The molecule consists of a six-membered benzene ring with a methyl group (CH₃) and an amino group (NH₂) attached. The presence of the amino group makes methylaniline a weak base.

Synthesis

Methylaniline can be synthesized by the reaction of aniline with methyl chloride in the presence of a base, such as sodium hydroxide. This reaction is known as N-alkylation.

Uses

Methylaniline is primarily used as a chemical intermediate in the synthesis of other chemicals. It is used in the production of dyes, pharmaceuticals, and polymers. In particular, it is used in the synthesis of methylene blue, a dye used in biology and medicine.

Safety

Exposure to methylaniline can cause skin and eye irritation, and prolonged exposure can lead to more serious health effects. It is classified as a hazardous substance and should be handled with care.
