4-Bromophenylhydrazine hydrochloride（Cat No.:R063778）is an aromatic hydrazine derivative featuring a bromine atom at the para position on the phenyl ring and existing as a stable hydrochloride salt. It is widely used as a synthetic intermediate in pharmaceutical, agrochemical, and dye chemistry. The hydrazine moiety offers nucleophilic reactivity, making it ideal for forming hydrazones, azo compounds, and heterocycles such as pyrazoles and triazoles. The hydrochloride form improves handling, solubility, and storage stability. This compound is particularly useful in building nitrogen-rich scaffolds for bioactive molecule development.
