Aplicaciones

2,3,4,5,6-Pentafluorobenzeneboronic acid is utilized in the palladium-catalyzed Suzuki reaction to synthesize several cross-coupled aromatic compounds, for example bis(pentafluorophenyl)-substituted thiophene and selenophene derivatives. It serves as an intermediate and raw material in pharmaceutical and chemical industry. It is also used in dyes and pigments. It can be used to prepare cyclic boronates of bifunctional compounds.

Notas

Moisture Sensitive. Store in cool and dry conditions in well sealed containers. Keep container tightly sealed.
