Chemical Structure
Description
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.
CATO supplies N-(1-(3-(pyrazin-2-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)thiophene-3-carboxamide (CAS 1396856-49-7), a certified reference material (molecular formula C17H17N5O2S, MW 355.41 g/mol) for analytical method development and quality control.
N-(1-(3-(pyrazin-2-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)thiophene-3-carboxamide (C17H17N5O2S) 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.
