(R)-4-Bromo-1-pyrrolidin-3-yl-1H-pyrazole dihydrochloride is a chiral brominated pyrazole derivative with a pyrrolidine substituent, commonly employed as a versatile intermediate in pharmaceutical and agrochemical synthesis. Its dihydrochloride salt form enhances stability and solubility, facilitating handling and storage. The compound’s stereospecific (R)-configuration is critical for applications requiring enantioselective activity, particularly in the development of bioactive molecules. The bromine moiety offers a reactive site for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies. High purity and well-defined stereochemistry ensure reproducibility in research applications. Suitable for use in ligand design and as a building block for heterocyclic compounds.
