General description
4-Mercaptophenylboronic acid is a stable boronic acid that can be used as a reagent in the Pd-catalyzed Suzuki-Miyaura cross-coupling reactions to prepare useful building blocks via C-C bond formation.
Application
4-Mercaptophenylboronic acid can be used to functionalize Fe3O4-C-Au magnetic microspheres to synthesize core−shell structure Fe3O4-C-Au magnetic microspheres for the selective enrichment of glycoproteins and glycopeptides.
Other Notes
may contain bis-4,4′-thiophenylboronic

Molecular recognition based on specific intermolecular interactions is essential for the design of sensors with high selectivity. Herein, we report the surface-enhanced Raman scattering (SERS) behaviour of 4-mercaptophenyl boronic acid (MPBA) on self-assembled silver nanoparticles and its interaction with d-glucose.

A fluorescent array based on the use of saccharide-functionalized multicolored quantum dots (s-QDs) and of 4-mercaptophenylboronic acid-functionalized MoS2 nanosheets (PBA-MoS2) was constructed for multiple identification and quantitation of lectins and bacteria. In this array, the fluorescence of the s-QDs is quenched by

A highly selective and sensitive colorimetric sensor based on aggregation-induced color change of 4-mercaptophenylboronic modified gold nanoparticles was designed for the determination of fluoride anion. The 4-mercaptophenylboronic modified gold nanoparticles were synthesized by a simple one-pot reaction. The aggregation process
