(E)-2-(2-chlorobenzyl)-6-styryl-4,5-dihydropyridazin-3(2H)-one CAS 1164564-01-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-2-(2-chlorobenzyl)-6-styryl-4,5-dihydropyridazin-3(2H)-one.

CATO supplies (E)-2-(2-chlorobenzyl)-6-styryl-4,5-dihydropyridazin-3(2H)-one (CAS 1164564-01-5), a certified reference material (molecular formula C19H17ClN2O, MW 324.80 g/mol) for analytical method development and quality control.

The molecular framework of (E)-2-(2-chlorobenzyl)-6-styryl-4,5-dihydropyridazin-3(2H)-one (C19H17ClN2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
