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-(Quinoxalin-2-ylsulfanyl)propanoic acid (CAS 187028-75-7), molecular formula C11H10N2O2S and molecular weight 234.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Quinoxalin-2-ylsulfanyl)propanoic acid (C11H10N2O2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-(Quinoxalin-2-ylsulfanyl)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.
