Description
Compared with other compounds in its class, the molecular weight of 286.26 g/mol gives Ethyl 4-(diethoxyphosphoryl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 4-(diethoxyphosphoryl)benzoate (CAS 17067-92-4), a certified reference material (molecular formula C13H19O5P, MW 286.26 g/mol) for analytical method development and quality control.
Ethyl 4-(diethoxyphosphoryl)benzoate (C13H19O5P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
As a certified reference material (CRM), Ethyl 4-(diethoxyphosphoryl)benzoate 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.
