Description
CATO manufactures 2-Hydroxy-4-methoxy phenyl boronic acid pinacol 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.
2-Hydroxy-4-methoxy phenyl boronic acid pinacol ester (CAS 2072801-99-9) is a high-purity analytical reference standard with the molecular formula C13H19BO4 and a molecular weight of 250.10 g/mol.
2-Hydroxy-4-methoxy phenyl boronic acid pinacol ester (C13H19BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
