Description

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
