Ethyl 2-amino-4-methylthiophene-3-carboxylate

The title compound, C8H11NO2S, crystallizes with two mol­ecules, A and B, in the asymmetric unit. Each molecule features an intramolecular N—H⋯O hydrogen bond and the same H atom is also involved in an intermolecular N—H⋯S bond to generate A + B dimers. Further N—H⋯O hydrogen bonds link the dimers into a [010] chain.
