(6-Chloroimidazo[1,2-b]pyridazin-3-yl)methanol

(6-Chloroimidazo[1,2-b]pyridazin-3-yl)methanol is the PubChem IUPAC identity for CID 57352521 and CAS 675580-49-1. Its molecular formula is C7H6ClN3O. PubChem records SMILES C1=CC(=NN2C1=NC=C2CO)Cl and InChIKey VZFRNQCOHYEZFL-UHFFFAOYSA-N. The official synonyms include “6-chloroimidazo[1,2-b]pyridazine-3-methanol,” confirming the earlier catalog syntax.

The fused bicyclic system combines an imidazole portion with a pyridazine ring and contains three nitrogens. Chlorine is bonded at position 6, while position 3 bears a hydroxymethyl carbon outside the fused rings. That side chain supplies the only oxygen and one of the seven carbons in C7H6ClN3O. PubChem represents all atoms as one neutral component, with no separate chloride and no encoded stereochemistry. Writing “pyridazine-3-methanol” compresses the same attachment expressed more explicitly by the parenthesized “pyridazin-3-yl)methanol” name. The bracket style around the fusion locants also changes typography only; CAS, formula, and graph preserve the same ring junctions.

When sending an Rlavie inquiry, retain CAS 675580-49-1 and the complete fused-ring name. Add the requested quantity and request-specific information required to distinguish the record. If a structure file is supplied, attach a MOL or SDF file and verify the ring fusion, 6-chloro position, and 3-hydroxymethyl bond against the official SMILES. CID 57352521 and InChIKey VZFRNQCOHYEZFL-UHFFFAOYSA-N can accompany the request as independent identifiers for this exact molecular graph.
