Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Bromo-2-methylphenyl)hydrazine hydrochloride.
(4-Bromo-2-methylphenyl)hydrazine hydrochloride (CAS 858209-27-5) is a high-purity analytical reference standard with the molecular formula C7H9BrN2HCl and a molecular weight of 237.53 g/mol.
The molecular framework of (4-Bromo-2-methylphenyl)hydrazine hydrochloride (C7H9BrN2HCl) is characterized by a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (4-Bromo-2-methylphenyl)hydrazine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
