4-Vinylphenylboronic Acid CAS 2156-04-9 chemical structure

Description

CATO manufactures 4-Vinylphenylboronic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

4-Vinylphenylboronic Acid (CAS 2156-04-9), molecular formula C8H9BO2 and molecular weight 147.97 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H9BO2, 4-Vinylphenylboronic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 147.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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