CAS 638-03-9: 3-Methylaniline hydrochloride
Description:3-Methylaniline hydrochloride, with the CAS number 638-03-9, is an organic compound that belongs to the class of aromatic amines. It is the hydrochloride salt of 3-methylaniline, which features a methyl group attached to the aniline structure at the meta position. This compound typically appears as a white to off-white crystalline solid and is soluble in water due to the presence of the hydrochloride group, which enhances its solubility compared to its free base form. 3-Methylaniline hydrochloride is primarily used in the synthesis of dyes, pigments, and pharmaceuticals. It exhibits basic properties due to the amino group, allowing it to participate in various chemical reactions, including electrophilic aromatic substitution. Safety considerations are important when handling this compound, as aromatic amines can be toxic and potentially carcinogenic. Proper safety measures, including the use of personal protective equipment and adequate ventilation, are recommended during its handling and use in laboratory or industrial settings.
