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. H2POH is mainly of pedagogical interest. Many phosphinous acids are known containing organic substituents. One example is diphenylphosphinous acid.
