| Abstract: | The study on physicochemical properties of oxytetracycline and oxytetracycline hydrochloride was done with differential scanning calorimetry and derivative thermogravimetry, including the onset temperatures of the melting, polymorphism, chemically combined water and fusion heat. The results showed that physiochemical parameter of oxytetracycline was identical with the standard substance and no morphotropy was found when oxytetracycline hydrochloride melted. |
