The molecule consists of a biphenyl framework in which one aromatic ring (ring A) bears a single substituent, while the other aromatic ring (ring B) remains unsubstituted. Ring A is numbered such that the bond connecting it to ring B is designated as A-1. At position A-4, a nitrogen atom is attached to ring A. This nitrogen is double-bonded to a carbon atom, which is in turn singly bonded to both a hydroxyl group and a carbonyl carbon. The carbonyl carbon is further bonded to another nitrogen atom that carries a methyl group and a 2-methylbutyl chain (-CH2-CH(CH3)-CH2-CH3).
