Abstract: | Objective: A method was described for the identification of related substances in Phenobarbital Sodium Injection with LC-MS. Methods: HPLC-MS method was used to determine the relative substances in Phenobarbital Sodium Injection. The mobile phase was methanol-0.5% acetic acid (60:40), flow rate was 0.25 mL/min; The method is more specific and accurate. It provides a scientific basis for the detection of stability of Phenobarbital Sodium Injection and the product quality under control. |
