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 (R)-3-Mercapto-2-((S)-5-thioxopyrrolidine-2-carboxamido)propanoic acid (CAS 148076-52-2), a certified reference material (molecular formula C8H12N2O3S2, MW 248.32 g/mol) for analytical method development and quality control.
Structurally, (R)-3-Mercapto-2-((S)-5-thioxopyrrolidine-2-carboxamido)propanoic acid (C8H12N2O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 248.32 g/mol, it falls into the medium-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).
As a certified reference material (CRM), (R)-3-Mercapto-2-((S)-5-thioxopyrrolidine-2-carboxamido)propanoic 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.
