Description
As a certified reference material (CRM), 3-Bromo-2-fluorothioanisole 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.
3-Bromo-2-fluorothioanisole (CAS 871353-01-4), molecular formula C7H6BrFS and molecular weight 221.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system, 3-Bromo-2-fluorothioanisole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
