Chemical Structure
Description
The molecular framework of Diethyl (difluoro(1-hydroxycyclohexyl)methyl)phosphonate (C11H21F2O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Diethyl (difluoro(1-hydroxycyclohexyl)methyl)phosphonate (CAS 191014-05-8) is a high-purity analytical reference standard with the molecular formula C11H21F2O4P and a molecular weight of 286.25 g/mol.
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 (difluoro(1-hydroxycyclohexyl)methyl)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.
