Chemical Structure
Description
CATO supplies N-(4-Acetylphenyl)-2-((3-phenyl-1,2,4-thiadiazol-5-yl)thio)acetamide (CAS 864856-27-9), a certified reference material (molecular formula C18H15N3O2S2, MW 369.46 g/mol) for analytical method development and quality control.
N-(4-Acetylphenyl)-2-((3-phenyl-1,2,4-thiadiazol-5-yl)thio)acetamide (C18H15N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
