Phosphinous acid is the inorganic compound with the formula H2POH. It exists, fleetingly, as a mixture with its less stable tautomer H3PO. These species have been generated by low temperature oxidation of phosphine with ozone.[1] H2POH is mainly of pedagogical interest. Many phosphinous acids are known containing organic substituents. One example is diphenylphosphinous acid.
