Chemical Structure
Description
CATO supplies 5-(2,2-Diphenylvinyl)-3-phenyl-1H-pyrazole (CAS 7470-31-7), a certified reference material (molecular formula C23H18N2, MW 322.40 g/mol) for analytical method development and quality control.
The molecular framework of 5-(2,2-Diphenylvinyl)-3-phenyl-1H-pyrazole (C23H18N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. 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.
