General description

N,N,N′,N′-Tetramethyl-p-phenylenediamine (TMPDA) is a redox reagent with low ionization potential widely used as an electron donor for photosystem I. It also acts as an electron acceptor in photosystem II.[1][2]

Application

N,N,N′,N′-Tetramethyl-p-phenylenediamine (TMPDA) can be used:
  • In the flow injection analysis of benzoyl peroxide.[3]
  • To study photoinduced electron transfer to halogenated solvents.[2]

Caution

May darken in storage.
