Chemical Structure

O-Ethyl benzothioate CAS 936-61-8 chemical structure

Description

O-Ethyl benzothioate (CAS 936-61-8), molecular formula C9H10OS and molecular weight 166.24 g/mol, is a CATO reference standard with documented purity and traceability.

O-Ethyl benzothioate (C9H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), O-Ethyl benzothioate 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.
