Chemical Structure
Description
Potassium thiazol-2-ylprolinate (CAS 1231949-74-8), molecular formula C8H9N2O2SK and molecular weight 236.33 g/mol, is a CATO reference standard with documented purity and traceability.
Potassium thiazol-2-ylprolinate (C8H9N2O2SK) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Potassium thiazol-2-ylprolinate 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.
