Description
As a certified reference material (CRM), 2-Chloro-4-fluoro-5-methylbenzenethiol 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.
CATO supplies 2-Chloro-4-fluoro-5-methylbenzenethiol (CAS 1208077-04-6), a certified reference material (molecular formula C7H6ClFS, MW 176.64 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-4-fluoro-5-methylbenzenethiol (C7H6ClFS) is characterized by sulfur-containing functionality, fluorine/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 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.
