Chemical Structure
Description
4,4,5,5-Tetraethyl-2-(furan-3-yl)-1,3,2-dioxaborolane (CAS 2769970-47-8) is a high-purity analytical reference standard with the molecular formula C14H23BO3 and a molecular weight of 250.14 g/mol.
The molecular framework of 4,4,5,5-Tetraethyl-2-(furan-3-yl)-1,3,2-dioxaborolane (C14H23BO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
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.
