5-(Thiophen-3-ylmethyl)-1,3,4-oxadiazole-2-thiol CAS 262856-02-0

Description

Based on its molecular formula C7H6N2OS2, 5-(Thiophen-3-ylmethyl)-1,3,4-oxadiazole-2-thiol contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies 5-(Thiophen-3-ylmethyl)-1,3,4-oxadiazole-2-thiol (CAS 262856-02-0), a certified reference material (molecular formula C7H6N2OS2, MW 198.27 g/mol) for analytical method development and quality control.

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.
