Chemical Structure
Description
The molecular framework of 2-(4-Bromo-3-thienyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C10H14BBrO2S) is characterized by a sulfone group, 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.
2-(4-Bromo-3-thienyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1310404-31-9) is a high-purity analytical reference standard with the molecular formula C10H14BBrO2S and a molecular weight of 289.00 g/mol.
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.
