Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
258516-84-6 ACN-052867 Phosphoric acid, chloromethyl bis(phenylmethyl) ester dibenzyl chloromethyl phosphate (CAS 258516-84-6) is a high-purity analytical reference standard with the molecular formula C15H28ClO4P and a molecular weight of 338.81 g/mol.
258516-84-6 ACN-052867 Phosphoric acid, chloromethyl bis(phenylmethyl) ester dibenzyl chloromethyl phosphate (C15H28ClO4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
