4-Bromo-1H-pyrazole-3-carboxylic acid（Cat No.:L042312）is a halogenated heterocyclic compound commonly used as a synthetic intermediate in medicinal and agrochemical research. Featuring a pyrazole ring substituted with a bromine atom at the 4-position and a carboxylic acid at the 3-position, it exhibits dual functionality for diverse chemical transformations. The bromine allows for palladium-catalyzed cross-coupling reactions, while the carboxylic acid supports amide bond formation and esterification. Its structure makes it valuable for the design of kinase inhibitors, anti-inflammatory agents, and other bioactive molecules in lead optimization and SAR studies.
