4-Ethoxy-3-fluoro-2-formylphenylboronic acid CAS 1246404-48-7

Description

The occurrence of 4-Ethoxy-3-fluoro-2-formylphenylboronic 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.

4-Ethoxy-3-fluoro-2-formylphenylboronic acid (CAS 1246404-48-7), molecular formula C9H10BFO4 and molecular weight 211.98 g/mol, is a CATO reference standard with documented purity and traceability.

4-Ethoxy-3-fluoro-2-formylphenylboronic acid (C9H10BFO4) 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, 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 4-Ethoxy-3-fluoro-2-formylphenylboronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
