Chemical Structure

2-amino-6-methyl-pyridine-3-thiol CAS 33761-31-8 chemical structure

Description

As a certified reference material (CRM), 2-amino-6-methyl-pyridine-3-thiol 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.

2-amino-6-methyl-pyridine-3-thiol (CAS 33761-31-8), molecular formula C6H8N2S and molecular weight 140.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-amino-6-methyl-pyridine-3-thiol (C6H8N2S) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 140.21 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.
