PTC catalyst 

Uses

Methyltriphenylphosphonium Bromide is a lipophilic molecule with a cation allowing for it to be used to deliver molecules to specific cell components. Also considered an antineoplastic agent.

Purification Methods

If the solid is sticky, wash it with *C6H6 and dry it in a vacuum over P2O5.
