3-(-4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid benzyl ester (CAS 880157-10-8), molecular formula C20H23BO4 and molecular weight 338.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(-4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid benzyl ester (C20H23BO4) is characterized by a flavonoid core, 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).
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.
