Physico-chemical properties and stability of trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1H- dibenz[2,3:6,7]oxepino[4,5-c]pyrrolidine maleate.
The physico-chemical properties of trans-5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1H- dibenz[2,3:6,7]oxepino[4,5-c]pyrrolidine maleate (Org 5222), a new potential antipsychotic compound, were studied by interpretation of its spectra (UV,IR,NMR,mass), X-ray analysis, thermal properties, solubilities and partition coefficient. Analytical methods such as GLC and TLC were developed for use in stability tests. Crystalline Org 5222 was shown to be stable with respect to heat. Only excessive exposure to light was shown to induce degradation of crystalline Org 5222. In solutions of pH 1, 4 and 7 only slight degradation was observed at high temperature or after exposure to light.
