Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-{[(2,3-Dioxo-1,2,3,4-tetrahydroquinoxalin-6-yl)-sulfonyl]amino}propanoic acid (CAS 939746-10-8) is a high-purity analytical reference standard with the molecular formula C11H11N3O6S and a molecular weight of 313.29 g/mol.
The molecular framework of 3-{[(2,3-Dioxo-1,2,3,4-tetrahydroquinoxalin-6-yl)-sulfonyl]amino}propanoic acid (C11H11N3O6S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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), 3-{[(2,3-Dioxo-1,2,3,4-tetrahydroquinoxalin-6-yl)-sulfonyl]amino}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.
