Decyl(triphenyl)phosphonium (DTPP) is the organophosphorus cation with the formula C10H21P(C6H5)3+.

It forms the basis for many mitochondrial-targeted drugs, including MitoQ, MitoE, and SkQ.

It binds to the mitochondrial matrix by insertion into the inner membrane.

[1][2] DTPP itself can cause mitochondrial swelling in kidney tissue, an action possibly related to increased membrane permeability.
