Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3-Chloro-4-(methylsulfonyl)phenyl)-3-((S)-3-oxocyclopentyl)-N-(pyrazin-2-yl)propanamide (CAS 625114-41-2), molecular formula C19H20ClN3O4S and molecular weight 421.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Chloro-4-(methylsulfonyl)phenyl)-3-((S)-3-oxocyclopentyl)-N-(pyrazin-2-yl)propanamide (C19H20ClN3O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-(3-Chloro-4-(methylsulfonyl)phenyl)-3-((S)-3-oxocyclopentyl)-N-(pyrazin-2-yl)propanamide 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.
