Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-((5-Cyclopentyl-1,2,4-oxadiazol-3-yl)methyl)-3-(pyrrolidin-1-ylsulfonyl)pyridin-2(1H)-one.
CATO supplies 1-((5-Cyclopentyl-1,2,4-oxadiazol-3-yl)methyl)-3-(pyrrolidin-1-ylsulfonyl)pyridin-2(1H)-one (CAS 1396875-74-3), a certified reference material (molecular formula C17H22N4O4S, MW 378.45 g/mol) for analytical method development and quality control.
Structurally, 1-((5-Cyclopentyl-1,2,4-oxadiazol-3-yl)methyl)-3-(pyrrolidin-1-ylsulfonyl)pyridin-2(1H)-one (C17H22N4O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 378.45 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-((5-Cyclopentyl-1,2,4-oxadiazol-3-yl)methyl)-3-(pyrrolidin-1-ylsulfonyl)pyridin-2(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
