5-(2-(4-Chlorophenyl)-2-oxoethylidene)-2-imino-3-(o-tolyl)oxazolidin-4-one CAS 122975-87-5

Description

The occurrence of 5-(2-(4-Chlorophenyl)-2-oxoethylidene)-2-imino-3-(o-tolyl)oxazolidin-4-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-(2-(4-Chlorophenyl)-2-oxoethylidene)-2-imino-3-(o-tolyl)oxazolidin-4-one (CAS 122975-87-5), a certified reference material (molecular formula C18H13ClN2O3, MW 340.76 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H13ClN2O3, 5-(2-(4-Chlorophenyl)-2-oxoethylidene)-2-imino-3-(o-tolyl)oxazolidin-4-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 340.76 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.
