Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Diphenylphosphoryl)pentan-3-one.
1-(Diphenylphosphoryl)pentan-3-one (CAS 69803-57-2) is a high-purity analytical reference standard with the molecular formula C17H19O2P and a molecular weight of 286.31 g/mol.
Based on its molecular formula C17H19O2P, 1-(Diphenylphosphoryl)pentan-3-one contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 1-(Diphenylphosphoryl)pentan-3-one 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.
