Chemical Structure
Description
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.
2,4-dihydro-1h-[1,2,4]triazolo[3,4-c][1,4]benzothiazin-1-one 6289-04-9 AR-1D3615 (CAS 6289-04-9), molecular formula C11H22ClN5 and molecular weight 259.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-dihydro-1h-[1,2,4]triazolo[3,4-c][1,4]benzothiazin-1-one 6289-04-9 AR-1D3615 (C11H22ClN5) is characterized by a nitrile group, chlorine substitution. 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).
As a certified reference material (CRM), 2,4-dihydro-1h-[1,2,4]triazolo[3,4-c][1,4]benzothiazin-1-one 6289-04-9 AR-1D3615 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.
