Description
2-Bromo-6-(difluoromethoxy)thioanisole (CAS 1804895-99-5), molecular formula C8H7BrF2OS and molecular weight 269.11 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-6-(difluoromethoxy)thioanisole (C8H7BrF2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Bromo-6-(difluoromethoxy)thioanisole 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.
