1-{4-[1,2-diphenyl-2-(<I>p-</I>tolyl)vinyl]phenyl}-1<I>H</I>-pyrrole-2,5 -diketone CAS 1245606-71-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 441.52 g/mol gives 1-{4-[1,2-diphenyl-2-(<I>p-</I>tolyl)vinyl]phenyl}-1<I>H</I>-pyrrole-2,5 -diketone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-{4-[1,2-diphenyl-2-(<I>p-</I>tolyl)vinyl]phenyl}-1<I>H</I>-pyrrole-2,5 -diketone (CAS 1245606-71-6), a certified reference material (molecular formula C31H23NO2, MW 441.52 g/mol) for analytical method development and quality control.

The molecular framework of 1-{4-[1,2-diphenyl-2-(<I>p-</I>tolyl)vinyl]phenyl}-1<I>H</I>-pyrrole-2,5 -diketone (C31H23NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
