Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 193.07 g/mol gives (4-Chlorobenzyl)hydrazine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4-Chlorobenzyl)hydrazine hydrochloride (CAS 75333-04-9), molecular formula C7H9ClN2HCl and molecular weight 193.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Chlorobenzyl)hydrazine hydrochloride (C7H9ClN2HCl) is characterized by a nitrile group, chlorine 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4-Chlorobenzyl)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.
