Chemical Structure
Description
The occurrence of (3-(Cyclopentyloxy)-5-(trifluoromethoxy)phenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3-(Cyclopentyloxy)-5-(trifluoromethoxy)phenyl)boronic acid (CAS 1256346-04-9) is a high-purity analytical reference standard with the molecular formula C12H14BF3O4 and a molecular weight of 290.04 g/mol.
(3-(Cyclopentyloxy)-5-(trifluoromethoxy)phenyl)boronic acid (C12H14BF3O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
