Chemical Structure

(S)-1-phenylethane-1-thiol CAS 33877-11-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (S)-1-phenylethane-1-thiol (CAS 33877-11-1), a certified reference material (molecular formula C8H10S, MW 138.23 g/mol) for analytical method development and quality control.

The molecular framework of (S)-1-phenylethane-1-thiol (C8H10S) is characterized by sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

As a certified reference material (CRM), (S)-1-phenylethane-1-thiol 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.
