title: Identification of drugs and other toxic compounds from their ultraviolet spectra. Part III: Ultraviolet absorption properties of 22 structural groups.
abstract: The ultraviolet absorption spectra of 22 different chemical (structural) groups of drugs and toxic compounds were studied. This paper completes a three-part series in which more than 500 individual compounds have been grouped according to structure as it pertains to characteristics of the ultraviolet absorption scan. Each group has a typical absorption profile with respect to the number of bands between 200 and 340 nm, the intensity of the band(s), and the changes in absorption pattern with solvent and pH changes. Phenothiazines, xanthines, coumarins, quinolines, naphthalene derivatives. O-alkyl benzene derivatives, opiates, ergot alkaloids, benzodiazepines, and various heterocyclic compounds are among the groups of compounds covered in this paper.
