Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 279.02 g/mol gives Dibutyl (2-bromopropan-2-yl)boronate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dibutyl (2-bromopropan-2-yl)boronate (CAS 5271-86-3) is a high-purity analytical reference standard with the molecular formula C11H24BBrO2 and a molecular weight of 279.02 g/mol.
Dibutyl (2-bromopropan-2-yl)boronate (C11H24BBrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
As a certified reference material (CRM), Dibutyl (2-bromopropan-2-yl)boronate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
