CAS 1689-02-7 identifies Pyrrolidine-1-sulfonyl chloride, molecular formula C4H8ClNO2S. PubChem records this identity as CID 6483902, with SMILES C1CCN(C1)S(=O)(=O)Cl and InChIKey JRIQCVWTPGVBBH-UHFFFAOYSA-N. “1-Pyrrolidinesulfonyl chloride” is the PubChem Title, while the selected H1 is its official IUPAC naming form.
The saturated pyrrolidine ring contains four carbons and one nitrogen. Ring nitrogen is bonded directly to sulfur, which is also bonded to chlorine and two oxygen atoms. Both sulfur–oxygen bonds appear in double-bond notation in the standardized SMILES. The chlorine atom is covalently integrated into the same component rather than represented as a detached chloride counterion. Four ring carbons and eight hydrogens complete formula C4H8ClNO2S. PubChem encodes no second molecular fragment and no stereochemical layer. Placing the locant before “sulfonyl chloride” makes the nitrogen attachment explicit; the compact Title and the IUPAC form preserve the same ring-to-sulfur bond.
Begin an Rlavie inquiry with CAS 1689-02-7 and CID 6483902, then add the requested quantity and request-specific information. A MOL or SDF structure file can accompany a graph-led request; verify the pyrrolidine nitrogen, both sulfur-bound oxygens, and the covalent chlorine against C1CCN(C1)S(=O)(=O)Cl. InChIKey JRIQCVWTPGVBBH-UHFFFAOYSA-N supplies another exact comparison point before the message is linked to this single-component sulfonyl chloride record without ambiguity.
