Chemical Structure
Description
The molecular framework of 4,4,5,5-Tetramethyl-2-(1-(o-tolyl)vinyl)-1,3,2-dioxaborolane (C15H21BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4,4,5,5-Tetramethyl-2-(1-(o-tolyl)vinyl)-1,3,2-dioxaborolane (CAS 2169318-18-5) is a high-purity analytical reference standard with the molecular formula C15H21BO2 and a molecular weight of 244.14 g/mol.
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.
As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(1-(o-tolyl)vinyl)-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.
