Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-(3-Chlorophenyl)-8-((4-ethylphenyl)sulfonyl)-1,4,8-triazaspiro[4.5]dec-3-en-2-one (CAS 1189481-30-8), a certified reference material (molecular formula C21H22ClN3O3S, MW 431.94 g/mol) for analytical method development and quality control.
3-(3-Chlorophenyl)-8-((4-ethylphenyl)sulfonyl)-1,4,8-triazaspiro[4.5]dec-3-en-2-one (C21H22ClN3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
