CAS 5570-18-3: B-(2-Aminophenyl)boronic acid

2-Aminophenylboronic acid is an organic compound that can be used as a cross-coupling agent in the Suzuki coupling reaction. It has been used to synthesize amides and β-unsaturated ketones. It has also been used to prepare fluorescent molecules for use in clinical diagnostics. The phase transition temperature of 2-aminophenylboronic acid is approximately -6°C, which makes it useful for the synthesis of amides and β-unsaturated ketones at low temperatures. This compound is not reactive towards nucleophiles due to its acidic character, but it can undergo a nucleophilic attack when protonated. Its fluorescence assay can be used to detect the presence of low concentrations of hydrogen sulfide gas in natural gas pipelines.
