Acifluorfen（Cat No.:R069266）is a diphenyl ether herbicide that inhibits protoporphyrinogen oxidase (PPO), a key enzyme in chlorophyll and heme biosynthesis. By blocking PPO, acifluorfen causes the accumulation of toxic intermediates that lead to membrane damage and rapid cell death in plants. It is primarily used for post-emergence control of broadleaf weeds and some grasses in crops like soybeans and peanuts. Acifluorfen’s mode of action makes it valuable in agricultural weed management and as a reference compound in herbicide research. It also supports studies on oxidative stress and plant metabolism.
