4-Iodopyridin-3-amine is identified by CAS 105752-11-2 and molecular formula C5H5IN2. PubChem resolves this CAS number to CID 819132. Its verified structure is represented by SMILES C1=CN=CC(=C1I)N and InChIKey ZJRSKTXMSIVNAU-UHFFFAOYSA-N. These values match the molecular formula, SMILES, and InChI recorded for this catalog entry.
The name specifies a six-membered pyridine ring containing one ring nitrogen, with an amino group at position 3 and iodine at position 4. The molecular formula accounts for five carbon atoms, five hydrogen atoms, one iodine atom, and two nitrogen atoms. One nitrogen belongs to the pyridine ring and the other to the amino group. The verified PubChem connectivity encodes the same adjacent 3-amino and 4-iodo substitution pattern without a separate counterion or salt component.
The equivalent wording 3-amino-4-iodopyridine describes the same verified connectivity, but the H1 adopts the PubChem title for consistent presentation. The two locants should remain attached to their respective substituents so this page is not confused with another iodopyridinamine isomer. CAS 105752-11-2, PubChem CID 819132, molecular formula C5H5IN2, SMILES C1=CN=CC(=C1I)N, and InChIKey ZJRSKTXMSIVNAU-UHFFFAOYSA-N form the verified identity set. Keeping the complete set together aligns the catalog name and structure record. Provide the full identifier set in an enquiry so the requested iodine and amino substitution pattern can be checked directly.
