The occurrence of 238403-28-6 poly(ethylene glycol) triphenylphosphine is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
238403-28-6 poly(ethylene glycol) triphenylphosphine (CAS 238403-28-6), molecular formula C18H33PC2H6O2 and molecular weight 342.50 g/mol, is a CATO reference standard with documented purity and traceability.
238403-28-6 poly(ethylene glycol) triphenylphosphine (C18H33PC2H6O2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
