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 (5-Ethoxy-2-fluoro-4-methylphenyl)boronic acid.
CATO supplies (5-Ethoxy-2-fluoro-4-methylphenyl)boronic acid (CAS 918813-07-7), a certified reference material (molecular formula C9H12BFO3, MW 198.00 g/mol) for analytical method development and quality control.
Structurally, (5-Ethoxy-2-fluoro-4-methylphenyl)boronic acid (C9H12BFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 198.00 g/mol, it falls into the medium-molecular-weight range. 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.
