Chemical Structure
Description
The molecular framework of 2-(3-Isopropoxy-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C16H25BO3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-(3-Isopropoxy-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1218789-75-3), molecular formula C16H25BO3 and molecular weight 276.18 g/mol, is a CATO reference standard with documented purity and traceability.
