The molecular framework of 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)isophthalaldehyde (C14H17BO4) 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 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).
5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)isophthalaldehyde (CAS 945865-80-5) is a high-purity analytical reference standard with the molecular formula C14H17BO4 and a molecular weight of 260.09 g/mol.
