Identification and differentiation of organic medicinal agents V. Quaternary Ammonium compounds

Identification tests have been presented for 23 compounds containing either one or two quaternary anmonium functional groups. The reactions of these compounds with ammonium reineckate, picric acid, and chloroplatinic acid have been studied and 54 adducts have been isolated and their melting ranges presented. In addition, microcrystal tests showed that many adducts possessed distinctive crystalline morphology. Photomicrographs are presented as a supplemental and additional parameter for characterication purposes.
