2,5-Dichloro-4-(methylthio)pyridine CAS 474824-43-6

Description

Compared with other compounds in its class, the molecular weight of 194.08 g/mol gives 2,5-Dichloro-4-(methylthio)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,5-Dichloro-4-(methylthio)pyridine (CAS 474824-43-6), a certified reference material (molecular formula C6H5Cl2NS, MW 194.08 g/mol) for analytical method development and quality control.

The molecular framework of 2,5-Dichloro-4-(methylthio)pyridine (C6H5Cl2NS) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution, 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).

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.

CATO manufactures 2,5-Dichloro-4-(methylthio)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
