The zwitterionic title compound, C12H17NO3S, is a reduced Schiff base derived from (S)-N-(2-hy­droxy­benzyl­idene)methio­nine. An intra­molecular inter­action between the N—H and carboxyl­ate groups forms a roughly planar (r.m.s. deviation = 0.1405 Å) five-membered ring containing the H(N), N, Cα, C(carboxyl­ate) and O atoms in a penta­gonal conformation. In the crystal, a supra­molecular triangle-shaped motif is generated by mol­ecules held together by O—H⋯O and N—H⋯O hydrogen bonds.
