In present study, a novel, simple, robust, stability-indicating, highly sensitive and specific reverse phase ultra-performance liquid chromatographic method was established and validated for the determination of ibrutinib using acquity charged surface hybrid C-18 (100 mm×2.1 mm, 1.7 μm) column with a mobile phase consisting of mixture of Eluent-A phosphate buffer, 0.1 % triethylamine, (pH 6.0) and Eluent-B acetonitrile with flow rate 0.3 ml min-1. The detection was monitored at 215 nm using photodiode array detector. Linearity was observed from 25 to 250 ng ml-1 (correlation of coefficient was 0.9999) with equation, y=100.1880x-130.8966. The observed limit of detection and limit of quantitation were 25 ng ml-1 and 50 ng ml-1 respectively. Ibrutinib was subjected to stress conditions comprising hydrolytic (acid, alkali and neutral), oxidative, photolytic and thermal degradation as per International council for harmonisation Q1 guidelines. The results showed that substantial degradation were observed in acid, base and peroxide degradation condition and resistant to neutral, photolytic and thermal degradation. This is first highly sensitive stability-indicating ultra-performance liquid chromatography method capable of separating ibrutinib and its ten degradation products at nano gram (ng) level. The method was validated as stated by International council for harmonisation guidelines.
