Description
CATO manufactures Carbonochloridic acid, (acetyloxy)methyl ester 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.
Carbonochloridic acid, (acetyloxy)methyl ester (CAS 133217-71-7), molecular formula C4H5ClO4 and molecular weight 152.53 g/mol, is a CATO reference standard with documented purity and traceability.
Carbonochloridic acid, (acetyloxy)methyl ester (C4H5ClO4) contains a carbohydrate-derived structure, 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.
