Sulfamoyl chloride

CAS 7778-42-9 identifies Sulfamoyl chloride, which PubChem records as CID 24499 with formula ClH2NO2S. Its standardized SMILES is NS(=O)(=O)Cl, and its InChIKey is QAHVHSLSRLSVGS-UHFFFAOYSA-N. PubChem gives “chlorosulfamic acid” as the Title and “sulfamoyl chloride” as the IUPAC name, tying both labels to one verified graph.

In the recorded connectivity, sulfur is the central atom. It is bonded to nitrogen, chlorine, and two oxygen atoms, with the SMILES showing both sulfur–oxygen bonds in double-bond notation. The nitrogen accounts for two hydrogens in ClH2NO2S; there are no carbon atoms in the formula. Chlorine is covalently attached within the same component rather than listed as a detached chloride. The official PubChem representation has no second molecular fragment and carries no encoded stereochemistry. These details distinguish the identity from names that might imply a carbon-bearing sulfonyl group. Formula order can vary between databases, but the element counts, CID, SMILES, and InChIKey remain the controlling references for this record.

Start an Rlavie inquiry with CAS 7778-42-9 and CID 24499, then state the requested quantity and request-specific information for the review. A MOL/SDF structure file or another structure file can be included when the inquiry originates from a drawn graph. Match its sulfur, nitrogen, oxygen, and chlorine connections to NS(=O)(=O)Cl. Quoting InChIKey QAHVHSLSRLSVGS-UHFFFAOYSA-N helps keep the submission aligned with this precise entry.
