Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Oxo-6-sulfamoyl-2,3-dihydro-1,3-benzoxazol-3-yl)propanoic acid.
3-(2-Oxo-6-sulfamoyl-2,3-dihydro-1,3-benzoxazol-3-yl)propanoic acid (CAS 929975-45-1) is a high-purity analytical reference standard with the molecular formula C10H10N2O6S and a molecular weight of 286.26 g/mol.
The molecular framework of 3-(2-Oxo-6-sulfamoyl-2,3-dihydro-1,3-benzoxazol-3-yl)propanoic acid (C10H10N2O6S) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-(2-Oxo-6-sulfamoyl-2,3-dihydro-1,3-benzoxazol-3-yl)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.
