Chemical Structure

2-(4-Chlorophenyl)-5-{2-[(4-methylphenyl)methanesulfonyl]phenyl}-1,3,4-oxadiazole CAS 339104-33-5 chemical structure

Description

2-(4-Chlorophenyl)-5-{2-[(4-methylphenyl)methanesulfonyl]phenyl}-1,3,4-oxadiazole (CAS 339104-33-5) is a high-purity analytical reference standard with the molecular formula C22H17ClN2O3S and a molecular weight of 424.90 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(4-Chlorophenyl)-5-{2-[(4-methylphenyl)methanesulfonyl]phenyl}-1,3,4-oxadiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
