5-{[5-(thiophen-3-yl)-2H-1,2,3,4-tetrazol-2-yl]methyl}-1,3,4-oxadiazole-2-thiol (C8H6N6OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 5-{[5-(thiophen-3-yl)-2H-1,2,3,4-tetrazol-2-yl]methyl}-1,3,4-oxadiazole-2-thiol (CAS 871497-66-4), a certified reference material (molecular formula C8H6N6OS2, MW 266.30 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.
