Description
CATO manufactures 4-Fluoro-2-methylbenzenethiol 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.
4-Fluoro-2-methylbenzenethiol (CAS 845823-04-3), molecular formula C7H7FS and molecular weight 142.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Fluoro-2-methylbenzenethiol (C7H7FS) is characterized by sulfur-containing functionality, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
