Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((5,6-Diphenyl-1,2,4-triazin-3-yl)thio)-1-(piperidin-1-yl)ethanone.
2-((5,6-Diphenyl-1,2,4-triazin-3-yl)thio)-1-(piperidin-1-yl)ethanone (CAS 309283-45-2), molecular formula C22H22N4OS and molecular weight 390.50 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-((5,6-Diphenyl-1,2,4-triazin-3-yl)thio)-1-(piperidin-1-yl)ethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-((5,6-Diphenyl-1,2,4-triazin-3-yl)thio)-1-(piperidin-1-yl)ethanone 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.
