5-(Methylsulfanyl)-1,2,3,4-thiatriazole CAS 52098-77-8

Description

Compared with other compounds in its class, the molecular weight of 133.20 g/mol gives 5-(Methylsulfanyl)-1,2,3,4-thiatriazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(Methylsulfanyl)-1,2,3,4-thiatriazole (CAS 52098-77-8), molecular formula C2H3N3S2 and molecular weight 133.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(Methylsulfanyl)-1,2,3,4-thiatriazole (C2H3N3S2) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
