3-(methanesulfonylmethyl)-5-(trichloromethyl)-1,2,4-oxadiazole CAS 1269152-41-1

Description

The occurrence of 3-(methanesulfonylmethyl)-5-(trichloromethyl)-1,2,4-oxadiazole is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(methanesulfonylmethyl)-5-(trichloromethyl)-1,2,4-oxadiazole (CAS 1269152-41-1), a certified reference material (molecular formula C5H5Cl3N2O3S, MW 279.53 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(methanesulfonylmethyl)-5-(trichloromethyl)-1,2,4-oxadiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
