Product Information
5-Iodo-2,3-dihydropyridazin-3-one corresponds to CAS 825633-94-1, molecular formula C4H3IN2O, and PubChem CID 16638330. The verified connectivity is SMILES C1=C(C=NNC1=O)I. PubChem supplies InChIKey UZWMMCWOUBWROK-UHFFFAOYSA-N for the same structure. These identifiers collectively define one iodinated pyridazinone record.
The six-membered pyridazine framework contains two adjacent nitrogen atoms and four carbon atoms. Its carbonyl oxygen is at position 3, and iodine is bonded at position 5. The 2,3-dihydro wording is part of the recorded tautomeric name and agrees with the hydrogen placement encoded in the PubChem structure. Formula C4H3IN2O accounts for four carbons, three hydrogens, one iodine, two nitrogens, and one oxygen. There is no separate counterion in the official graph. Both the iodine locant and the pyridazinone numbering are required to distinguish this compound from other iodinated diazine ketone arrangements.
Reference CAS 825633-94-1 in the inquiry form and keep the complete 2,3-dihydropyridazin-3-one name in the message. State the desired quantity and appropriate contact information, and include any question about identity documentation. If another system provides only a structure key, compare it with CID 16638330 or InChIKey UZWMMCWOUBWROK-UHFFFAOYSA-N before sending. Rlavie can rely on this set of references to tie the inquiry to the 5-iodo record. Formula C4H3IN2O alone is not sufficient to communicate the tautomeric description and substitution position captured by the full entry.
