Chemical Structure
Description
CATO supplies Phosphoric acid, diphenyl ester, silver(1+) salt (1:1) (CAS 22350-95-4), a certified reference material (molecular formula C12H10O4PAg, MW 357.05 g/mol) for analytical method development and quality control.
Phosphoric acid, diphenyl ester, silver(1+) salt (1:1) (C12H10O4PAg) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
