5-Bromo-4-chloro-2-phenylpyridazin-3(2H)-one CAS 1698-63-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-4-chloro-2-phenylpyridazin-3(2H)-one.

5-Bromo-4-chloro-2-phenylpyridazin-3(2H)-one (CAS 1698-63-1), molecular formula C10H6BrClN2O and molecular weight 285.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-4-chloro-2-phenylpyridazin-3(2H)-one (C10H6BrClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 5-Bromo-4-chloro-2-phenylpyridazin-3(2H)-one 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.
