Chemical Structure

3-Fluoro-4-methylbenzeneboronic acid pinacol ester, 97% CAS 903895-56-7 chemical structure

Description

The occurrence of 3-Fluoro-4-methylbenzeneboronic acid pinacol ester, 97% 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.

CATO supplies 3-Fluoro-4-methylbenzeneboronic acid pinacol ester, 97% (CAS 903895-56-7), a certified reference material (molecular formula C13H18BFO2, MW 236.09 g/mol) for analytical method development and quality control.

3-Fluoro-4-methylbenzeneboronic acid pinacol ester, 97% (C13H18BFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 3-Fluoro-4-methylbenzeneboronic acid pinacol ester, 97% 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.
