Chemical Structure

(Z)-2'-hydroxy-3'-(2-(1-(4-(hydroxymethyl)-3-methylphenyl)-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4-ylidene)hydrazineyl)-[1,1'-biphenyl]-3-carboxylic acid CAS 1396009-04-3 chemical structure

Description

(Z)-2'-hydroxy-3'-(2-(1-(4-(hydroxymethyl)-3-methylphenyl)-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4-ylidene)hydrazineyl)-[1,1'-biphenyl]-3-carboxylic acid (CAS 1396009-04-3), molecular formula C25H40N4O5 and molecular weight 476.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Z)-2'-hydroxy-3'-(2-(1-(4-(hydroxymethyl)-3-methylphenyl)-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4-ylidene)hydrazineyl)-[1,1'-biphenyl]-3-carboxylic acid (C25H40N4O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 (Z)-2'-hydroxy-3'-(2-(1-(4-(hydroxymethyl)-3-methylphenyl)-3-methyl-5-oxo-1,5-dihydro-4H-pyrazol-4-ylidene)hydrazineyl)-[1,1'-biphenyl]-3-carboxylic acid 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.
