(2-Bromophenyl)hydrazine hydrochloride (1:1)(CAS: 50709-33-6)

(2-Bromophenyl)hydrazine hydrochloride is a white crystalline solid with a molecular weight of approximately 243.04 g/mol. It is slightly soluble in water and ethanol. The compound is moderately reactive, particularly towards nucleophiles. It has a melting point of 175-177°C and is hygroscopic. Due to its bromine content, it is susceptible to hydrolysis under basic conditions.

(2-Bromophenyl)hydrazine hydrochloride can be synthesized by the reaction of 2-bromophenylhydrazine with hydrochloric acid. The synthesis involves condensing 2-bromophenylhydrazine with hydrochloric acid in a suitable solvent such as methanol or ethanol. The yield is typically around 85%, and the reaction is carried out under mild conditions to ensure selectivity and high purity.

(2-Bromophenyl)hydrazine hydrochloride finds applications in the pharmaceutical industry for the synthesis of various bioactive compounds. It is also used in the chemical industry for the production of dyes and pigments, as well as in the textile industry for dyeing and finishing. Additionally, it is utilized in research and development for its reactivity towards nucleophiles and its potential uses in sensor technology.

When handling (2-Bromophenyl)hydrazine hydrochloride, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The compound should be handled in a fume hood to minimize exposure to fumes. It is hygroscopic and can react with water and basic substances, so it should be stored in a dry, cool place, away from moisture and sources of heat. Emergency spill kits and safety data sheets (SDS) should be readily available in the laboratory for proper handling and disposal.
