Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl (3-((4-chloro-N-methylphenyl)sulfonamido)thiophene-2-carbonyl)glycinate (CAS 1251549-87-7), molecular formula C15H15ClN2O5S2 and molecular weight 402.87 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl (3-((4-chloro-N-methylphenyl)sulfonamido)thiophene-2-carbonyl)glycinate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
