CATO manufactures 4,4,5,5-Tetramethyl-2-(3-methyl-4-(trifluoromethyl)phenyl)-1,3,2-dioxaborolane 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.
4,4,5,5-Tetramethyl-2-(3-methyl-4-(trifluoromethyl)phenyl)-1,3,2-dioxaborolane (CAS 1126479-89-7) is a high-purity analytical reference standard with the molecular formula C14H18BF3O2 and a molecular weight of 286.10 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4,4,5,5-Tetramethyl-2-(3-methyl-4-(trifluoromethyl)phenyl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
