Chemical Structure
Description
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.
2-((5-Thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)methoxy)acetic acid (CAS 61320-74-9) is a high-purity analytical reference standard with the molecular formula C5H6N2O4S and a molecular weight of 190.18 g/mol.
2-((5-Thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)methoxy)acetic acid (C5H6N2O4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), 2-((5-Thioxo-4,5-dihydro-1,3,4-oxadiazol-2-yl)methoxy)acetic acid 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.
