Application

3,5-Dimethylpyrazole-4-boronic acid pinacol ester can be used:
  • To synthesize 9H-pyrimido[4,5-b]indole and aryl-benzimidazole based BET bromodomain and extra terminal (BET) protein inhibitors.
  • To prepare naphthalimide based photo-exchangeable photochromic fluorescent molecules.
  • As a reactant to develop DNA-encoded chemical libraries by palladium-catalyzed Suzuki coupling reaction with DNA-linked aryl halides.
