Used primarily as an intermediate in organic synthesis, especially in the production of dyes, pharmaceuticals, and agrochemicals. It reacts readily with amines and alcohols to form amides and esters, making it valuable for constructing complex molecules. In pharmaceutical manufacturing, it serves as a building block for certain local anesthetics and anti-inflammatory agents. Its reactivity allows for the introduction of the 4-aminobenzoyl group into larger structures, facilitating the development of novel compounds with targeted biological activity.
