Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 270.26 g/mol gives Diethyl (1-oxo-1-phenylpropan-2-yl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Diethyl (1-oxo-1-phenylpropan-2-yl)phosphonate (CAS 10409-56-0), a certified reference material (molecular formula C13H19O4P, MW 270.26 g/mol) for analytical method development and quality control.
Diethyl (1-oxo-1-phenylpropan-2-yl)phosphonate (C13H19O4P) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Diethyl (1-oxo-1-phenylpropan-2-yl)phosphonate 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.
