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.

4-[(Pyridin-3-yl)methyl]-3-(trifluoromethyl)-4,5-dihydro-1H-1,2,4-triazole-5-thione (CAS 294853-60-4), molecular formula C9H7F3N4S and molecular weight 260.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-[(Pyridin-3-yl)methyl]-3-(trifluoromethyl)-4,5-dihydro-1H-1,2,4-triazole-5-thione (C9H7F3N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 260.24 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
