Chemical Structure
Description
The occurrence of (2,6-Difluorophenyl)phosphonic acid is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,6-Difluorophenyl)phosphonic acid (CAS 1206195-94-9), molecular formula C6H5F2O3P and molecular weight 194.07 g/mol, is a CATO reference standard with documented purity and traceability.
(2,6-Difluorophenyl)phosphonic acid (C6H5F2O3P) 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, 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.
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 (2,6-Difluorophenyl)phosphonic acid 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.
