Chemical Structure

6-Methyl-2,4-bis(methylthio)pyridin-3-amine CAS 134991-79-0 chemical structure

Description

6-Methyl-2,4-bis(methylthio)pyridin-3-amine (CAS 134991-79-0), molecular formula C8H12N2S2 and molecular weight 200.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Methyl-2,4-bis(methylthio)pyridin-3-amine (C8H12N2S2) 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 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), 6-Methyl-2,4-bis(methylthio)pyridin-3-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.
