4,4-Difluorpentanoic acid is an intermediate in the synthesis of amantadine hydrochloride. It is also used as a food additive to inhibit proteolytic enzymes and to produce alkyl esters. 4,4-Difluorpentanoic acid can be used as a competitive inhibitor of serine proteases and cysteine proteases. The compound binds reversibly to the active site of these enzymes and inhibits their activity by competing with the natural substrate for binding. This compound is often used in combination with other protease inhibitors such as phenylmethanesulfonyl fluoride or N-phenylmaleimide.
