Chemical Structure
Description
As a certified reference material (CRM), 1-(Benzenesulfonyl)pyrrolidine-2-carboxylic acid 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.
CATO supplies 1-(Benzenesulfonyl)pyrrolidine-2-carboxylic acid (CAS 88425-47-2), a certified reference material (molecular formula C11H13NO4S, MW 255.29 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(Benzenesulfonyl)pyrrolidine-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
