Chemical Structure

3-(methylsulfanyl)pyridine CAS 18794-33-7 chemical structure

Description

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.

3-(methylsulfanyl)pyridine (CAS 18794-33-7) is a high-purity analytical reference standard with the molecular formula C6H7NS and a molecular weight of 125.19 g/mol.

The molecular framework of 3-(methylsulfanyl)pyridine (C6H7NS) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3-(methylsulfanyl)pyridine 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.
