Chemical Structure

4-Methylpyridine-2-thiol CAS 18368-65-5 chemical structure

Description

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.

4-Methylpyridine-2-thiol (CAS 18368-65-5), molecular formula C6H7NS and molecular weight 125.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 4-Methylpyridine-2-thiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
