Chemical Structure
Description
1-(Diethoxyphosphorylmethyl)-2,3,4,5,6-pentafluoro-benzene (C11H12F5O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(Diethoxyphosphorylmethyl)-2,3,4,5,6-pentafluoro-benzene (CAS 125138-11-6) is a high-purity analytical reference standard with the molecular formula C11H12F5O3P and a molecular weight of 318.18 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.
