Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 2-(triphenylphosphoranyl)propanoate (CAS 2689-62-5) is a high-purity analytical reference standard with the molecular formula C22H22O2PBr and a molecular weight of 429.29 g/mol.
Methyl 2-(triphenylphosphoranyl)propanoate (C22H22O2PBr) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Methyl 2-(triphenylphosphoranyl)propanoate 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.
