CATO supplies 2,7-Dimethyl-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one (CAS 41914-67-4), a certified reference material (molecular formula C7H7N3OS, MW 181.21 g/mol) for analytical method development and quality control.
2,7-Dimethyl-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one (C7H7N3OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
