trans-2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)styrene beta-styrylboronic acid pinacol ester trans-styrylboronic acid, pinacol ester trans-2-phenylvinylboronic acid pinacol ester trans-beta-styrylboronic acid pinacol ester (E)-Phenylethenylboronic acid, pinacol ester (E)-4,4,5,5-Tetramethyl-2-(2-phenylvinyl)-1,3,2-dioxaborolane 83947-56-2 (CAS 83947-56-2), molecular formula C14H25BO2 and molecular weight 236.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of trans-2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)styrene beta-styrylboronic acid pinacol ester trans-styrylboronic acid, pinacol ester trans-2-phenylvinylboronic acid pinacol ester trans-beta-styrylboronic acid pinacol ester (E)-Phenylethenylboronic acid, pinacol ester (E)-4,4,5,5-Tetramethyl-2-(2-phenylvinyl)-1,3,2-dioxaborolane 83947-56-2 (C14H25BO2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
