Description
As a certified reference material (CRM), 2-Bromo-5-(difluoromethyl)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.
CATO supplies 2-Bromo-5-(difluoromethyl)phenol (CAS 1261760-40-0), a certified reference material (molecular formula C7H5BrF2O, MW 223.01 g/mol) for analytical method development and quality control.
2-Bromo-5-(difluoromethyl)phenol (C7H5BrF2O) contains 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.
