Description
As a certified reference material (CRM), 7-Fluoro-1-benzothiophene-2-carbonyl chloride 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.
7-Fluoro-1-benzothiophene-2-carbonyl chloride (CAS 2035458-56-9), molecular formula C9H4ClFOS and molecular weight 214.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Fluoro-1-benzothiophene-2-carbonyl chloride (C9H4ClFOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
