Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 182.41 g/mol gives trans-2-(4-Chlorophenyl)vinylboronic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
trans-2-(4-Chlorophenyl)vinylboronic Acid (CAS 154230-29-2) is a high-purity analytical reference standard with the molecular formula C8H8BClO2 and a molecular weight of 182.41 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, trans-2-(4-Chlorophenyl)vinylboronic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
