The molecular framework of 2-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-oxoacetic acid 13C, 15N2 (C9[13C]H12[15N]2O5S) 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).
CATO supplies 2-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-oxoacetic acid 13C, 15N2 (CAS 73181-56-3), a certified reference material (molecular formula C9[13C]H12[15N]2O5S, MW 275.26 g/mol) for analytical method development and quality control.
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), 2-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-oxoacetic acid 13C, 15N2 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.
