Pentafluoropropionic acid ke mokelikeli o se nang 'mala o monko o monate. Ke asiti e matla e sebetsanang le metsi ho etsa hydrofluoric acid. Pentafluoropropionic acid ke ntho e matla ea oxidizing e sebetsanang le lintho tse ngata tsa manyolo le litšepe. E bola ha mocheso o le holimo 'me e senya.

 

Pentafluoropropionic acid e na le mefuta e mengata ea tšebeliso indastering ea lik'hemik'hale. E boetse e sebelisoa ho lokisa lisebelisoa tsa polymer tse kang polytetrafluoroethylene le polymerized perfluoropropylene. Pentafluoropropionic acid e boetse e sebelisoa e le electroplating, rust inhibitor le moemeli oa phekolo ea holim'a metsi.

 

Ho na le mekhoa e 'maloa ea ho lokisa pentafluoropropionic acid, e' ngoe ea eona e atisang ho fumanoa ke karabelo ea boron trifluoride le hydrogen fluoride. Khase ea hydrogen fluoride e fetisetsoa ka har'a tharollo ea boron trifluoride 'me e itšoara ka mocheso o loketseng ho qetella e fumane pentafluoropropionic acid.
