Jul 31 2019 12:54PM Normal Acknowledged This is an odd tautomer for 4-aminopyridine, the vast majority of other data sources have the aromatic form. Drugbank also have the same odd tautomer, and don't know if you took the structure from them, or the other way around. I haven't checked using search tools, or checked SMILES etc for the record, since it could be that the underlying data is right, just that it's rendered oddly. If it were me, I'd draw the structure in the aromatic form.
Both tautomers collapse to the same InChI, so I was able to amend the structure to the more common representation.
