Description
As a certified reference material (CRM), 1,2-Bis(trifluoromethyl)-3-(difluoromethoxy)-5-ethylbenzene 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.
1,2-Bis(trifluoromethyl)-3-(difluoromethoxy)-5-ethylbenzene (CAS 1805528-00-0) is a high-purity analytical reference standard with the molecular formula C11H8F8O and a molecular weight of 308.17 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1,2-Bis(trifluoromethyl)-3-(difluoromethoxy)-5-ethylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.17 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.
