n-(5-Methyl-1,3,4-thiadiazol-2-yl)-2-(1,1,3-trioxo-2,3-dihydro-1lambda6,2-benzothiazol-2-yl)acetamide (CAS 663169-17-3), molecular formula C12H10N4O4S2 and molecular weight 338.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of n-(5-Methyl-1,3,4-thiadiazol-2-yl)-2-(1,1,3-trioxo-2,3-dihydro-1lambda6,2-benzothiazol-2-yl)acetamide (C12H10N4O4S2) 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), n-(5-Methyl-1,3,4-thiadiazol-2-yl)-2-(1,1,3-trioxo-2,3-dihydro-1lambda6,2-benzothiazol-2-yl)acetamide 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.
