Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
S-(3,5-dichlorophenyl) ethanethioate (CAS 1379311-78-0), molecular formula C8H6Cl2OS and molecular weight 221.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of S-(3,5-dichlorophenyl) ethanethioate (C8H6Cl2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), S-(3,5-dichlorophenyl) ethanethioate 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.
