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-(Benzyloxy)-2,4-difluoro-5-methylphenyl]boronic acid (CAS 2096331-91-6), molecular formula C14H13BF2O3 and molecular weight 278.06 g/mol, is a CATO reference standard with documented purity and traceability.
[3-(Benzyloxy)-2,4-difluoro-5-methylphenyl]boronic acid (C14H13BF2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures [3-(Benzyloxy)-2,4-difluoro-5-methylphenyl]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.
