Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R)-(3-Chloro-2-hydroxypropyl)phosphonic acid (CAS 221627-94-7) is a high-purity analytical reference standard with the molecular formula C3H8ClO4P and a molecular weight of 174.52 g/mol.
(R)-(3-Chloro-2-hydroxypropyl)phosphonic acid (C3H8ClO4P) contains a phosphate ester group, a carboxylic acid group, an ether linkage, 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.
CATO manufactures (R)-(3-Chloro-2-hydroxypropyl)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.
