Abstract: In the title compound, C₉H₁₀N₂O₄S, which is an important intermediate for the preparation of antitumor platinum drugs, the dioxolane ring adopts an envelope conformation with the C atom bonded to the thienyl ring at the flap position. Intramolecular N-HO and C-HO hydrogen bonds result in the formation of two five-membered rings having envelope conformations. In the crystal structure, intermolecular N-HO and C-HO hydrogen bonds link the molecules into a three-dimensional network.
