Catalysis (organometallic chemistry)- Used to generate highly reactive metal catalysts by stabilizing cationic metal species. Polymer chemistry- Helps in olefin polymerization reactions. Electrochemistry- Used as an electrolyte component due to its stability. Ion pairing studies- Ideal for studying free ions because it minimizes ion interaction.

Its main purpose is to act as a non-interfering counterion allowing chemists to work with highly reactive or sensitive positively charged species without unwanted side reactions.

It is a weakly coordinating anion salt meaning the bulky borate ion interacts very weakly with metal centers. The large fluorinated phenyl groups make it highly stable non-reactive and lipophilic.
