PRODUCT INTRODUCTION
Description
4-Bromopyrazole is a pyrazole compound. Its structure consists of three carbon atoms and two nitrogen atoms forming a five-membered ring, with a reactive group bromine atom. 4-Bromopyrazole can be used as a raw material for organic synthesis or as a reagent for chemical reactions. It can be used as a catalyst to promote the synthesis of peptides and participate in transition metal catalysis, and can also be used to prepare other heterocyclic compounds such as 1,4′-bipyrazole and 4-bromo-1-(2-chloroethyl)-1H-pyrazole.
