5-Bromopyridine-3-carboxylic acid(CAT: R037173) is a halogenated heteroaromatic compound featuring a pyridine ring substituted with a bromine atom at the 5-position and a carboxylic acid group at the 3-position. This bifunctional molecule is a valuable intermediate in medicinal and agrochemical synthesis, offering sites for selective functionalization. The bromine enables cross-coupling reactions such as Suzuki, Stille, or Sonogashira couplings, while the carboxylic acid allows for further derivatization into esters, amides, or bioactive frameworks. It is widely used in the development of nitrogen-containing scaffolds, ligands, and pharmaceutical building blocks.
