Chemical Structure
Description
2-(2-Bromobenzyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 149989-79-7) is a high-purity analytical reference standard with the molecular formula C13H18BBrO2 and a molecular weight of 297.00 g/mol.
2-(2-Bromobenzyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H18BBrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
