(Z)-5-(2-Benzylidenehydrazinyl)-4-chloropyridazin-3(2H)-one CAS 91063-66-0

Description

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

CATO supplies (Z)-5-(2-Benzylidenehydrazinyl)-4-chloropyridazin-3(2H)-one (CAS 91063-66-0), a certified reference material (molecular formula C11H9ClN4O, MW 248.67 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H9ClN4O, (Z)-5-(2-Benzylidenehydrazinyl)-4-chloropyridazin-3(2H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), (Z)-5-(2-Benzylidenehydrazinyl)-4-chloropyridazin-3(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
