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 4-((Cyclopentylamino)methyl)-N-(1-ethylpyrrolidin-3-yl)benzenesulfonamide (CAS 1336912-32-3), a certified reference material (molecular formula C18H29N3O2S, MW 351.51 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-((Cyclopentylamino)methyl)-N-(1-ethylpyrrolidin-3-yl)benzenesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 351.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4-((Cyclopentylamino)methyl)-N-(1-ethylpyrrolidin-3-yl)benzenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
