Summary
A new stability-indicating method using reverse-phase high-performance liquid chromatography (RP-HPLC) quantifies satranidazole. This method identifies degradation products under various stress conditions, ensuring pharmaceutical quality control.
Area of Science:
- Analytical Chemistry
- Pharmaceutical Sciences
Background:
- Satranidazole is an important antimicrobial agent.
- Assessing drug stability is crucial for pharmaceutical quality control and patient safety.
Purpose of the Study:
- To develop and validate a stability-indicating RP-HPLC method for satranidazole quantification.
- To characterize stress-induced degradation products of satranidazole using LC-MS.
Main Methods:
- RP-HPLC separation on a HiQ Sil C18 column with a methanol:formic acid mobile phase.
- UV detection at 317 nm.
- Stress degradation studies (acidic, alkaline, oxidative, thermal, photolytic) followed by LC-MS analysis.
Main Results:
- The RP-HPLC method showed excellent linearity (R²=0.999) from 5-30 μg/mL.
- Satranidazole significantly degraded under alkaline and photolytic conditions.
- LC-MS facilitated tentative identification of major degradants and proposed degradation pathways.
Conclusions:
- The developed RP-HPLC method is suitable for routine stability assessment of satranidazole.
- The method effectively separates satranidazole from its degradation products, aiding pharmaceutical quality control.
