Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3-(Ethoxymethyl)-5-fluorophenyl)boronic acid (CAS 1704063-74-0), molecular formula C9H12BFO3 and molecular weight 198.00 g/mol, is a CATO reference standard with documented purity and traceability.
(3-(Ethoxymethyl)-5-fluorophenyl)boronic acid (C9H12BFO3) contains 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.
CATO manufactures (3-(Ethoxymethyl)-5-fluorophenyl)boronic 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.
