Chemical Structure
Description
3-Bromo-4-((trifluoromethyl)thio)phenol (C7H4BrF3OS) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-Bromo-4-((trifluoromethyl)thio)phenol (CAS 1639457-45-6), molecular formula C7H4BrF3OS and molecular weight 273.07 g/mol, is a CATO reference standard with documented purity and traceability.
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), 3-Bromo-4-((trifluoromethyl)thio)phenol 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.
