Chemical Structure
Description
1-Bromo-3,5-bis(phenylmethoxy)benzene (CAS 128924-04-9) is a high-purity analytical reference standard with the molecular formula C20H17BrO2 and a molecular weight of 369.25 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, 1-Bromo-3,5-bis(phenylmethoxy)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.25 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-Bromo-3,5-bis(phenylmethoxy)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.
