2-Amino-3-methoxybenzoic acid（Cat No.:R017189）is an aromatic carboxylic acid featuring an amino group at the 2-position and a methoxy group at the 3-position of a benzoic acid core. This off-white to light yellow crystalline compound is moderately soluble in water and organic solvents. It serves as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. The presence of both electron-donating groups (amino and methoxy) enhances its reactivity in electrophilic substitution and coupling reactions. It is also used in developing bioactive molecules and in coordination chemistry for ligand design.
