Description

4-Bromophenylhydrazine hydrochloride (CAS No. 41931-18-4) is a high-purity organic compound with the molecular formula C₆H₈BrClN₂, widely used in pharmaceutical and chemical research. This white to off-white crystalline powder is a derivative of phenylhydrazine, featuring a bromine substituent at the para-position, enhancing its reactivity in synthetic applications. With a molecular weight of 223.50 g/mol, it is soluble in water and polar organic solvents, making it versatile for laboratory use. Ideal for coupling reactions, heterocycle synthesis, and as a precursor for dyes and agrochemicals, this reagent is rigorously tested for quality (HPLC, NMR) to ensure consistency. Store in a cool, dry place under inert conditions to maintain stability.

Application

4-Bromophenylhydrazine hydrochloride is a key intermediate in the synthesis of indoles, pyrazoles, and other nitrogen-containing heterocycles, which are foundational structures in drug discovery. It is employed in the preparation of dyes, pigments, and agrochemicals due to its reactive hydrazine moiety. Researchers also utilize it in cross-coupling reactions to introduce bromophenyl groups into complex molecules. Its stability and solubility make it suitable for both small-scale and industrial applications.
