Ion pair chromatography was used for quantifying bendamustine hydrochloride (BH) in its marketed vial. The permissive objective was to investigate time duration for which highly susceptible drug content of the marketed vial remained stable after reconstitution. However, the method could also be used to measure extremely low levels of drug in rat plasma and a pharmacokinetic study was accordingly conducted to further showcase method's applicability. Optimized separation was achieved on C-18 Purospher ® STAR (250 mm × 4.6 mm, 5 μm particle size) column. Mobile phase flowing at 1.5 mL/min consisted of 5 mM sodium salt of octane sulfonic acid dissolved in methanol, water and glacial acetic acid (55:45:0.075) maintained at pH 6. Detection was carried out at 233 nm with BH eluting after 7.8 min. Validation parameters were determined as per ICH guidelines. Limit of detection and limit of quantification were found to be 0.1 µg/mL and 0.33 µg/mL, respectively. The recoveries were 98-102% in bulk and 85-91% in plasma. The developed method was specific for BH, and utilized for assessing its short-term stability in physiologic solvents and forced degradation products in acid, base, oxidative, light and temperature induced stress environments.
