The title compound, C10H11N2O2P·H2O, contains a tetra­coordinate penta­valent P atom. The phosphinate group plays a predominant role in the cohesion of the crystal structure by forming chains along the b axis via inter­molecular C—H⋯O hydrogen bonds. These chains are connected by O—H⋯O and N—H⋯O hydrogen bonding involving the lattice water.
