Chemical Structure
Description
The occurrence of 3,5-Dimethyl-2-methoxyphenylboronic acid pinacol ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Dimethyl-2-methoxyphenylboronic acid pinacol ester (CAS 2121512-20-5), a certified reference material (molecular formula C15H23BO3, MW 262.15 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3,5-Dimethyl-2-methoxyphenylboronic acid pinacol ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.15 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.
