Application

2,5-Thiophenediylbisboronic acid can be used:
  • As a reactant in the metal catalyzed Suzuki cross coupling reactions.
  • To prepare 2,5-bis(2-pyridyl)thiophene, a thiophene based ligand which is used in the design of fluorescent mercury-sensor.
  • To fabricate graphene-based biosensors for the detection of glucose and Escherichia coli in a complex medium.
