Are there alternatives to barium difluoride (CAS: 7787-32-8) in synthesis?

There are several alternatives to barium difluoride (CAS: 7787-32-8) in synthesis, including calcium difluoride and magnesium difluoride, which can serve similar purposes in certain applications. However, the choice of alternative depends on specific experimental conditions and requirements. For instance, in applications requiring high purity and stability, alternatives like potassium difluoride might be considered.
