Chemical Structure

1-Methyl-3-(methylthio)-1H-1,2,4-triazol-5-amine CAS 51108-35-1 chemical structure

Description

1-Methyl-3-(methylthio)-1H-1,2,4-triazol-5-amine (CAS 51108-35-1), molecular formula C4H8N4S and molecular weight 144.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Methyl-3-(methylthio)-1H-1,2,4-triazol-5-amine (C4H8N4S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 144.20 g/mol, it falls into the low-molecular-weight range. 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), 1-Methyl-3-(methylthio)-1H-1,2,4-triazol-5-amine 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.
