Thiophene-2-carbothioamide is the PubChem IUPAC name for CID 737237 and CAS 20300-02-1. The verified molecular formula is C5H5NS2, the SMILES is C1=CSC(=C1)C(=S)N, and the InChIKey is HDXYHAPUCGQOBX-UHFFFAOYSA-N. PubChem’s Title, “2-thiophenecarbothioamide,” describes the same connectivity in a compact naming form.
A five-membered thiophene ring contributes four carbons and one sulfur atom. At ring position 2, the attached carbothioamide group adds the fifth carbon, one nitrogen, and a second sulfur. The explicit C(=S)N segment is decisive: formula C5H5NS2 contains no oxygen, so the verified graph is a thioamide rather than the oxygen-bearing carboxamide suggested by the old URL wording. PubChem encodes the substance as a single neutral component and does not specify stereochemistry. The ring sulfur and thioamide sulfur occupy different bonding environments, even though both appear in the same elemental formula. CAS, CID, and the full SMILES therefore resolve the suffix correction and separate this record from related thiophene amides.
When sending an Rlavie inquiry, cite CAS 20300-02-1 and the preferred carbothioamide name. Provide the requested quantity plus request-specific information for matching the intended identity. A MOL/SDF structure file can accompany the message; confirm that its exocyclic carbon is double-bonded to sulfur and bonded to nitrogen. CID 737237 and InChIKey HDXYHAPUCGQOBX-UHFFFAOYSA-N give two further references before Rlavie connects the inquiry to this record.
