Chemical Structure

(2E,3E)-1-{[1,1'-biphenyl]-4-yl}-2-[2-(2,5-dimethoxyphenyl)hydrazin-1-ylidene]-3-(methoxyimino)propan-1-one CAS 866048-95-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E,3E)-1-{[1,1'-biphenyl]-4-yl}-2-[2-(2,5-dimethoxyphenyl)hydrazin-1-ylidene]-3-(methoxyimino)propan-1-one.

CATO supplies (2E,3E)-1-{[1,1'-biphenyl]-4-yl}-2-[2-(2,5-dimethoxyphenyl)hydrazin-1-ylidene]-3-(methoxyimino)propan-1-one (CAS 866048-95-5), a certified reference material (molecular formula C24H23N3O4, MW 417.46 g/mol) for analytical method development and quality control.

The molecular framework of (2E,3E)-1-{[1,1'-biphenyl]-4-yl}-2-[2-(2,5-dimethoxyphenyl)hydrazin-1-ylidene]-3-(methoxyimino)propan-1-one (C24H23N3O4) 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 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.

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.
