What is Diphenylphosphinic acid (1707-03-5) used for?

Diphenylphosphinic acid (DPPA, hdpp) is an organophosphinic acid compound characterized by its white fine crystalline solid appearance. It is known for its reactivity and utility in various chemical processes, including its role as a flame-retardant and promoter for palladium catalytic systems. The thermal degradation of DPPA has been studied using thermogravimetric analysis (TGA), and it can engage in reactions with cadmium nitrate to form coordination polymers. Additionally, DPPA can be ortho-lithiated to create mono ortho-functionalized derivatives and biphenyl-2,2′-diylbis(phenylphosphinic acid) through copper-catalyzed coupling.
