Background: Impurities may reduce antibacterial activity and affect clinical efficacy, However, there has been no report on the impurity of clorprenaline and bromhexine capsules.

Objective: In order to determine the impurities in compound clorprenaline and bromhexine capsules.

Methods: A new stability-indicating HPLC method was established. A Boston Green ODS column was used, and the UV detection was 225nm.

Results: The established method was highly specific, sensitive, accurate, and suitable for routine quality control of clorprenaline and bromhexine capsules. The structures of unknown impurities were characterized by the MS/MS data.

Conclusion: These results provide a sufficient basis for our subsequent study on the safety of Compound Clorprenaline and Bromhexine Capsules and also provide ideas for the impurity research of other compound preparations.

Keywords: Clorprenaline, bromhexine capsules, impurity, HPLC, validation, 2d lc-q-tof ms.
