CATO supplies 4-Bromo-2-[(2Z)-2-(4-chlorophenyl)-2-(methoxyimino)ethyl]-5-(cyclohexylamino)-2,3-dihydropyridazin-3-one (CAS 477860-47-2), a certified reference material (molecular formula C19H22BrClN4O2, MW 453.76 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2-[(2Z)-2-(4-chlorophenyl)-2-(methoxyimino)ethyl]-5-(cyclohexylamino)-2,3-dihydropyridazin-3-one (C19H22BrClN4O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Bromo-2-[(2Z)-2-(4-chlorophenyl)-2-(methoxyimino)ethyl]-5-(cyclohexylamino)-2,3-dihydropyridazin-3-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.
