Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,5-Dichloro-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (CAS 2557358-67-3), molecular formula C12H15BCl2O3 and molecular weight 288.96 g/mol, is a CATO reference standard with documented purity and traceability.

3,5-Dichloro-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (C12H15BCl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 3,5-Dichloro-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol 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.
