Popis: It is shown that the drug teraphthal should be considered as a mixture of the octasodium salt of cobalt(II) 2,3,9,10,16,17,23,24-octacarboxyphthalocyanine (OCPC) and its oxidation product (component A) with the octasodium salt of OCPC and products from the extensive destruction of a substance with a similar elemental composition (component B). The composition can be estimated quantitatively using (i) the results of elemental analysis (H, N, Co) and (ii) PMR in combination with measurement of the weight loss on drying.
