paraanisidine

Paraanisidine, also known as 4-methoxyaniline or p-anisidine, is an organic compound with the chemical formula CH3OC6H4NH2. It is an aniline derivative where a methoxy group is attached to the para position of the benzene ring relative to the amino group. It appears as a white to light brown crystalline solid.

This compound is sparingly soluble in water but readily dissolves in organic solvents like ethanol and ether. Paraanisidine is an important intermediate in the synthesis of various dyes, pigments, and pharmaceuticals. It is particularly used in the production of azo dyes, which are known for their vibrant colors.

In terms of its properties, paraanisidine is a weak base due to the presence of the amino group. It can undergo typical reactions of aromatic amines, such as diazotization and acylation. It is considered moderately toxic and should be handled with care, avoiding skin contact and inhalation of dust. Safety precautions, including the use of personal protective equipment, are recommended when working with this chemical. Its primary applications lie in industrial chemical synthesis, contributing to the production of a wide range of colored materials and active pharmaceutical ingredients.
