5-((1,3-Diphenyl-1H-pyrazol-4-yl)methylene)-3-(4-methylbenzyl)-2-thioxothiazolidin-4-one CAS 624723-11-1

Description

CATO supplies 5-((1,3-Diphenyl-1H-pyrazol-4-yl)methylene)-3-(4-methylbenzyl)-2-thioxothiazolidin-4-one (CAS 624723-11-1), a certified reference material (molecular formula C27H21N3OS2, MW 467.61 g/mol) for analytical method development and quality control.

Based on its molecular formula C27H21N3OS2, 5-((1,3-Diphenyl-1H-pyrazol-4-yl)methylene)-3-(4-methylbenzyl)-2-thioxothiazolidin-4-one contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 467.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
