3-Aminophenylboronic acid monohydrate

3-Aminophenylboronic acid monohydrate is a phenylboronic acid derivative. 3-Aminophenylboronic acid monohydrate reacts covalently with cis-diol groups of glycoproteins, enabling selective capture and detection of glycoproteins through fluorescence quenching of APBA-functionalized copper nanoclusters^[1]. In Vitro:3-Aminophenylboronic acid (5 h) monohydrate successfully conjugates to bovine serum albumin-protected copper nanoclusters via EDC/NHS coupling, as confirmed by multiple spectroscopic and zeta potential analyses^[1].
3-Aminophenylboronic acid monohydrate-functionalized copper nanoclusters (5-220 nM OB) act as a highly sensitive and selective fluorescence sensor for ovalbumin, with a linear detection range of 5-220 nM, a detection limit of 2.60 nM, and accurate quantification in chicken egg white and human urine samples with high recoveries^[1].
