The occurrence of 5-(3-Methyl-1,2,4-thiadiazol-5-yl)-1,3,4-oxadiazol-2-amine is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(3-Methyl-1,2,4-thiadiazol-5-yl)-1,3,4-oxadiazol-2-amine (CAS 1448123-69-0), molecular formula C5H5N5OS and molecular weight 183.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-(3-Methyl-1,2,4-thiadiazol-5-yl)-1,3,4-oxadiazol-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
As a certified reference material (CRM), 5-(3-Methyl-1,2,4-thiadiazol-5-yl)-1,3,4-oxadiazol-2-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
