Description

5-Bromo-1-methyl-1H-pyrazole-3-carboxylic acid features a brominated pyrazole core with a methyl group at the N1 position and a carboxylic acid at C3, delivering enhanced electron-withdrawing character and synthetic versatility. This bench-stable scaffold integrates readily into medicinal chemistry campaigns requiring halogenated heterocycles.

Application

5-Bromo-1-methyl-1H-pyrazole-3-carboxylic acid serves as a versatile building block for the synthesis of bioactive heterocycles, enabling direct functionalization at the pyrazole core. The carboxylic acid group facilitates amide formation and esterification, while the bromine substituent supports palladium-catalyzed cross-coupling reactions. Its bench-stable nature and compatibility with standard synthetic protocols make it ideal for medicinal chemistry campaigns and API intermediate development.
