1-(3-クロロフェニル)-5-(2,4-ジヒドロキシベンゾイル)ピリジン-2(1H)-オンの結晶構造解析
This study reports the X-ray crystal structure of the compound C18H12ClNO4. The chlorophenyl substituent exhibits positional disorder across two orientations, with site occupancies of 0.331(8) and 0.669(8). An intramolecular hydrogen bond is observed between a hydroxyl group and the acyclic carbonyl moiety. Within the crystal lattice, intermolecular O-H···O and C-H···O hydrogen bonding interactions link molecules into extended chains propagating along the [110] direction, generating a characteristic ladder-type supramolecular motif.
The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
