Chemical Structure
Description
1-(2-Bromo-1,1-difluoroethyl)-3,5-bis(trifluoromethyl)benzene (CAS 1447671-72-8) is a high-purity analytical reference standard with the molecular formula C10H5BrF8 and a molecular weight of 357.04 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 1-(2-Bromo-1,1-difluoroethyl)-3,5-bis(trifluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1-(2-Bromo-1,1-difluoroethyl)-3,5-bis(trifluoromethyl)benzene 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.
