    摘要: Disclosed is a method for producing 2-amino-5-iodobenzoic acid wherein 2-aminobenzoic acid (A) and a molecular iodine (B) are reacted in a liquid phase in the presence of an oxidant. Hydrogen peroxide is preferably used as the oxidant. This method does not require a step for refining 2-amino-5-iodobenzoic acid or a step for recovering iodine, and enables to economically advantageously produce high-quality 2-amino-5-iodobenzoic acid with high yield. The thus-produced 2-amino-5-iodobenzoic acid can be advantageously used as a pharmaceutical intermediate, an agricultural chemical, a raw material for functional chemicals or the like.
