Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its functional groups—bromine, hydroxyl, and ester—allow for selective modifications through cross-coupling reactions, nucleophilic substitutions, and ester hydrolysis, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid pyridine scaffold and ease of derivatization. Also utilized in agrochemical research for designing novel active ingredients with improved metabolic stability and target specificity.
