摘要：

In the title compound, C11H11NO4S, the thiazine ring adopts a distorted half-chair conformation. The enolic H atom is involved in an intramolecular O-H center dot center dot center dot O hydrogen bond, forming a six-membered ring. Molecules are linked through weak intermolecular C-H center dot center dot center dot O hydrogen bonds, resulting in chains lying along the b axis.
