title: Methyl 2-ethyl-4-hydr-oxy-2H-1,2-benzo-thia-zine-3-carboxyl-ate 1,1-dioxide.
abstract: In the title compound, C(12)H(13)NO(5)S, the thia-zine ring adopts a half chair conformation and an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, leading to zigzag chains along the b axis.
