Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3-Bromophenyl)diphenylphosphine oxide (CAS 10212-04-1) is a high-purity analytical reference standard with the molecular formula C18H14BrOP and a molecular weight of 357.18 g/mol.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, (3-Bromophenyl)diphenylphosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.18 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.
CATO manufactures (3-Bromophenyl)diphenylphosphine oxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
