Description

CATO supplies 2-[(1E)-2-(4-Chlorophenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 2-[2-(4-Chlorophenyl)vinyl]-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane 223919-54-8 Trans-2-(4-Chlorophenyl)vinylboronic acid pinacol ester (CAS 223919-54-8), a certified reference material (molecular formula C14H24BClO2, MW 270.60 g/mol) for analytical method development and quality control.

The molecular framework of 2-[(1E)-2-(4-Chlorophenyl)ethenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 2-[2-(4-Chlorophenyl)vinyl]-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane 223919-54-8 Trans-2-(4-Chlorophenyl)vinylboronic acid pinacol ester (C14H24BClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
