3-Bromopyrazole（Cat No.:R061021）is a halogenated heterocyclic compound with the molecular formula C3H3BrN2, featuring a pyrazole ring substituted with a bromine atom at the 3-position. It appears as a white to off-white solid and serves as a versatile intermediate in pharmaceutical, agrochemical, and materials chemistry. The bromine atom provides a reactive site for further functionalization through cross-coupling reactions such as Suzuki or Buchwald-Hartwig couplings. Its electron-rich pyrazole ring is commonly found in bioactive molecules, making 3-bromopyrazole a valuable scaffold for the synthesis of kinase inhibitors, anti-inflammatory agents, and other therapeutic candidates.
