Chemical Structure

2-(Ethylthio)pyridine CAS 19006-76-9 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.

2-(Ethylthio)pyridine (CAS 19006-76-9), molecular formula C7H9NS and molecular weight 139.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 2-(Ethylthio)pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO manufactures 2-(Ethylthio)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.
