Chemical Structure
Description
The occurrence of 1,3,4-Oxadiazole-2-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3,4-Oxadiazole-2-sulfonamide (CAS 90774-48-4) is a high-purity analytical reference standard with the molecular formula C2H3N3O3S and a molecular weight of 149.13 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, an ether linkage, 1,3,4-Oxadiazole-2-sulfonamide is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
