(3,6-Dichloropyridazin-4-yl)methanol

(3,6-Dichloropyridazin-4-yl)methanol is identified by CAS 29360-81-4 and molecular formula C5H4Cl2N2O. PubChem resolves this CAS number to CID 20225791. The verified structure is represented by SMILES C1=C(C(=NN=C1Cl)Cl)CO and InChIKey PGICESQILFHKHS-UHFFFAOYSA-N. These values match the molecular formula, SMILES, and InChI stored for this catalog record.

The name specifies a pyridazine ring bearing chlorine atoms at positions 3 and 6 and a hydroxymethyl group at position 4. The molecular formula accounts for five carbon atoms, four hydrogen atoms, two chlorine atoms, two nitrogen atoms, and one oxygen atom. The PubChem connectivity contains the same adjacent ring nitrogens, both chlorine substituents, and the carbon-oxygen fragment expressed in the methanol name. No separate counterion or salt component appears in the verified structure representation.

For consistent identification, retain the parentheses, both chlorine locants, and the 4-yl methanol designation in the product name. This record should remain distinct from other dichloropyridazine methanol positional isomers. CAS 29360-81-4, PubChem CID 20225791, molecular formula C5H4Cl2N2O, SMILES C1=C(C(=NN=C1Cl)Cl)CO, and InChIKey PGICESQILFHKHS-UHFFFAOYSA-N form the verified identity set for this page. Keeping that fully verified set together aligns the human-readable name with the machine-readable connectivity. Include this complete identifier set in a quotation or custom-synthesis enquiry so the intended positional isomer can be reviewed precisely.
