چکیده
In the title compound, C11H14N2O2S, the thia-zolidine ring has an envelope conformation with the C atom bonded to the carb-oxy-lic acid group at the flap. Two C atoms of the thia-zolidine ring adopt S conformations. In the crystal, O-H⋯N hydrogen bonds between the amine and carb-oxy-lic acid groups construct a helical chain structure along the a-axis direction. The chains are further connected via weak C-H⋯π contacts, forming a layer parallel to the ac plane.
