Description
As a certified reference material (CRM), (4-Amino-3-methoxyphenyl)diethylphosphine oxide 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.
(4-Amino-3-methoxyphenyl)diethylphosphine oxide (CAS 1198014-23-1) is a high-purity analytical reference standard with the molecular formula C11H18NO2P and a molecular weight of 227.24 g/mol.
(4-Amino-3-methoxyphenyl)diethylphosphine oxide (C11H18NO2P) contains an amide group, 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 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.
