Description
CATO manufactures 3,3-Dichloro-2-(phosphonomethyl)acrylic 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.
3,3-Dichloro-2-(phosphonomethyl)acrylic acid (CAS 122279-84-9), molecular formula C4H5Cl2O5P and molecular weight 234.96 g/mol, is a CATO reference standard with documented purity and traceability.
3,3-Dichloro-2-(phosphonomethyl)acrylic acid (C4H5Cl2O5P) contains a carbohydrate-derived structure, a phosphate ester group, chlorine 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.
