Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl (1-Phenylethyl)phosphonate.
Diethyl (1-Phenylethyl)phosphonate (CAS 33973-48-7), molecular formula C12H19O3P and molecular weight 242.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H19O3P, Diethyl (1-Phenylethyl)phosphonate contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.25 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.
CATO manufactures Diethyl (1-Phenylethyl)phosphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
