[1,1'-Binaphthalene]-2,2'-dithiol

[1,1'-Binaphthalene]-2,2'-dithiol corresponds to CAS 102555-71-5, molecular formula C20H14S2, and molecular weight 318.5. PubChem resolves the CAS to a single compound, CID 625302. Its verified graph is written as SMILES C1=CC=C2C(=C1)C=CC(=C2C3=C(C=CC4=CC=CC=C43)S)S, and InChIKey PQTIXYILPGIIHM-UHFFFAOYSA-N identifies the same structure. The record contains one molecular component.

The framework consists of two naphthalene units joined through their respective 1 positions. Each naphthalene bears a thiol group at position 2, giving the symmetric 2,2'-dithiol description and accounting for both sulfur atoms in C20H14S2. The bracket and prime marks are meaningful punctuation: they distinguish positions on the two linked ring systems. PubChem's entry does not specify a stereochemical layer, so this page should not add an axial configuration. The draft also corrects the current title's missing opening bracket without changing molecular identity.

For a well-defined Rlavie inquiry, provide the normalized full name, CAS 102555-71-5, and the requested quantity, along with a MOL or SDF structure file. Rlavie can compare the graph with PubChem CID 625302, the complete SMILES, and InChIKey PQTIXYILPGIIHM-UHFFFAOYSA-N before reviewing request-specific details. Both the 1,1' biaryl connection and the two 2-position thiol groups should be confirmed. A generic label such as “binaphthalene dithiol” leaves those attachments unspecified, while formula C20H14S2 alone cannot distinguish another sulfur placement.
