Chemical Structure
Description
CATO supplies 5-(Acetylimino)-4,5-dihydro-4-methyl-1,3,4-thiadiazole-2-sulfonic Acid-d3 (CAS 1795143-17-7), a certified reference material (molecular formula C5H4D3N3O4S2, MW 240.28 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H4D3N3O4S2, 5-(Acetylimino)-4,5-dihydro-4-methyl-1,3,4-thiadiazole-2-sulfonic Acid-d3 contains deuterium isotope labeling, a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.28 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).
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.
