5-Chloro-3-iodopyridazine

5-Chloro-3-iodopyridazine is the compound identified by CAS Registry Number 1616070-38-2 and molecular formula C4H2ClIN2. Rlavie’s stored identity has been checked against PubChem CID 90238038. The verified structure is represented by the SMILES string C1=C(C=NN=C1I)Cl and the InChIKey HICXXHDGLABUAZ-UHFFFAOYSA-N. This structure contains a pyridazine ring bearing iodine at the 3-position and chlorine at the 5-position.

The locants and halogen assignments are part of the compound identity. They distinguish this record from 3-chloro-6-iodopyridazine, other chloro-iodopyridazine positional isomers and compounds containing only one of the two halogens. The molecular formula, CAS number, PubChem CID and structure keys should therefore be compared as a complete set. The cited SMILES represents a neutral compound and does not include a separate counterion or salt component.

To obtain a quotation or request a custom-synthesis assessment, send Rlavie the exact compound identity, required quantity, project scale and any structure or analytical documentation that must be followed. If your organization uses a different synonym or internal code, include the corresponding drawing so it can be checked against CAS 1616070-38-2 and PubChem CID 90238038. Availability, lead time, specification and deliverable analytical documents will be evaluated for the specific inquiry and should be confirmed in Rlavie’s written response.
