5-((Pyridin-3-ylmethyl)thio)-4H-1,2,4-triazol-3-amine CAS 710312-67-7

Description

Compared with other compounds in its class, the molecular weight of 207.26 g/mol gives 5-((Pyridin-3-ylmethyl)thio)-4H-1,2,4-triazol-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-((Pyridin-3-ylmethyl)thio)-4H-1,2,4-triazol-3-amine (CAS 710312-67-7), molecular formula C8H9N5S and molecular weight 207.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-((Pyridin-3-ylmethyl)thio)-4H-1,2,4-triazol-3-amine (C8H9N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
