Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
4,4,5,5-Tetraethyl-2-(furan-2-yl)-1,3,2-dioxaborolane (CAS 2769970-52-5) 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-2-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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 4,4,5,5-Tetraethyl-2-(furan-2-yl)-1,3,2-dioxaborolane 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.
