Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(p-Tolyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide.
4-(p-Tolyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide (CAS 1341010-36-3), molecular formula C13H11N3O3S and molecular weight 289.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(p-Tolyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide (C13H11N3O3S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 4-(p-Tolyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide 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.
