Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Ethyl-2,6-difluorophenyl)boronic acid.
(4-Ethyl-2,6-difluorophenyl)boronic acid (CAS 2244428-33-7) is a high-purity analytical reference standard with the molecular formula C8H9BF2O2 and a molecular weight of 185.96 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (4-Ethyl-2,6-difluorophenyl)boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.96 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.
