title: X-ray crystallographic and gas chromatographic--mass spectrometric studies on norpropoxyphene.
abstract: The crystal structure of norpropoxyphene maleate is presented. The conformation is discussed in relation to similar compounds. A gas chromatographic--mass spectrometric investigation indicates that earlier proposed metabolites may be formed during the gas chromatographic separation.
