Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive bromomethyl groups. These groups allow for easy attachment to other molecules through alkylation or cross-coupling reactions. Commonly employed in the preparation of functionalized aromatic compounds, especially in drug discovery for building complex molecular frameworks. Also utilized in polymer chemistry as a cross-linking agent to modify resin properties. Its carboxylic acid functionality enables salt formation or esterification, enhancing its versatility in organic synthesis.
