Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and kinase inhibitors. Commonly employed in agrochemical research for designing novel pesticides due to its halogenated pyridine structure, which enhances bioactivity. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies, where the bromo and chloro substituents allow further functionalization via cross-coupling reactions like Suzuki or Buchwald-Hartwig. Its ester group facilitates transformation into carboxylic acids or amides, enabling diverse derivatization for drug discovery.
