The occurrence of Benzo[c][1,2,5]thiadiazol-5-yl(1,5-dioxa-9-azaspiro[5.5]undecan-9-yl)methanone is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Benzo[c][1,2,5]thiadiazol-5-yl(1,5-dioxa-9-azaspiro[5.5]undecan-9-yl)methanone (CAS 1351618-77-3), a certified reference material (molecular formula C15H17N3O3S, MW 319.38 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Benzo[c][1,2,5]thiadiazol-5-yl(1,5-dioxa-9-azaspiro[5.5]undecan-9-yl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
