Chemical Structure
Description
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.
2-(4-bromobenzyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 477841-90-0) is a high-purity analytical reference standard with the molecular formula C13H24BBrO2 and a molecular weight of 303.04 g/mol.
The molecular framework of 2-(4-bromobenzyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H24BBrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
