TPAP or tetrapropylammonium perruthenate is a chemical compound. This ruthenium compound is used in organic chemistry as a mild oxidizing agent for alcohols to aldehydes. The oxidation generates water that can be removed by adding molecular sieves. TPAP is expensive and used in catalytic amounts. The catalytic cycle is maintained by adding a stoichiometric amount of re-oxidant such as N-methylmorpholine N-oxide.
