Chemical Structure
Description
2-(3,4-Difluoro-5-methoxyphenyl)ethane-1-thiol (CAS 1379363-71-9) is a high-purity analytical reference standard with the molecular formula C9H10F2OS and a molecular weight of 204.24 g/mol.
The molecular framework of 2-(3,4-Difluoro-5-methoxyphenyl)ethane-1-thiol (C9H10F2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(3,4-Difluoro-5-methoxyphenyl)ethane-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.
