(6-Chloropyridazin-3-yl)methanamine hydrochloride

(6-Chloropyridazin-3-yl)methanamine hydrochloride is the PubChem title for CAS 1420961-44-9. The unique result is CID 71301632 with molecular formula C5H7Cl2N3. Page and PubChem structure fields agree on SMILES C1=CC(=NN=C1CN)Cl.Cl, InChI InChI=1S/C5H6ClN3.ClH/c6-5-2-1-4(3-7)8-9-5;/h1-2H,3,7H2;1H, and InChIKey KJBDLAXXKHEKMF-UHFFFAOYSA-N. The dot-separated chloride component is part of the verified salt identity.

The parent ring is pyridazine, characterized by two adjacent ring nitrogen atoms. A chlorinated ring position appears at carbon 6, and a methanamine side chain is attached at position 3. The molecular formula contains two chlorine atoms because one chlorine is covalently bonded to the ring and the second belongs to the hydrochloride component. That component separation is visible in both the SMILES dot and the two-part InChI, so the entry should not be reduced to the corresponding free-base formula.

A request for this salt should specify (6-Chloropyridazin-3-yl)methanamine hydrochloride and CAS 1420961-44-9 together. PubChem CID 71301632 or InChIKey KJBDLAXXKHEKMF-UHFFFAOYSA-N can accompany a structure file to preserve both the ring substitution and hydrochloride component. The semicolon in the InChI separates the parent structure from hydrogen chloride and is therefore an identity-bearing feature. Rlavie can compare that submitted identity with the exact two-component record shown here. This page avoids transferring identifiers from a similarly named free base or another chloropyridazine arrangement.
