Chemical Structure

2-(o-Tolyl)ethanethioamide CAS 34243-66-8 chemical structure

Description

CATO supplies 2-(o-Tolyl)ethanethioamide (CAS 34243-66-8), a certified reference material (molecular formula C9H11NS, MW 165.26 g/mol) for analytical method development and quality control.

The molecular framework of 2-(o-Tolyl)ethanethioamide (C9H11NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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-(o-Tolyl)ethanethioamide 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.
