The calcium and magnesium salts of chlortetracycline were found to be readily soluble in methanol containing either calcium chloride or magnesium chloride. This fact was applied to the isolation of chlortetracycline from cultured broths. The CaCl2 complex of chlortetracycline-Ca salt was obtained in a crystalline form, its empirical formula subsequently determined as (C22H21N2O8Cl•Ca) 1/2 CaCl2. This product was very readily soluble in methanol. Similarly, the MgCl2 complex of chlortetracycline-Mg salt, (C22H21N2O8ClMg) 1/2 MgCl2 was also obtained.
