General description

Pyridinium based ionic liquid

Application

4MBPBF4 has been used in the preparation of the SWNT-polymer composite films to improve the dispersion of SWNTs and conductivity of the composites (SWNT= singlewalled carbon nanotubes). The use of 4MBPBF4 as a reaction media during derivatization of dimethyl sulfate with dibenzazepine, accelerates the rate of the reaction. It can also be used to modify carbon paste electrode, which leads to high sensitivity, selectivity and low detection limit for both potassium ferricyanide and dopamine by cyclic voltammetric technique.
