Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(P-tolyl)-3-(4-(trifluoromethyl)phenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine.

6-(P-tolyl)-3-(4-(trifluoromethyl)phenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine (CAS 477857-06-0), molecular formula C18H13F3N4S and molecular weight 374.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-(P-tolyl)-3-(4-(trifluoromethyl)phenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine (C18H13F3N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
