Objective: A state of the art, robust and environmentally benign stability indicating assay method (SIAM) has been developed for model drug Lenalidomide (LEN). Methods: A Green metrics assessment was conducted by environment assessment tool (EAT), analytical method volume intensity (AMVI) and Ecosolvent® tool. Successful chromatographic separation was accomplished on a Thermo C18 GAC column having dimensions of 4.6×150 mm and 3μ particle size using green solvents viz., methanol and acetate buffer in the ratio of 85:15. Results: The obtained EAT score and AMVI were 32.19 and 24 mL respectively. A green SIAM was developed and it was validated as per ICH Q2 (R1) guidelines. Quality by Design (QbD) approach was incorporated at validation stage to prove the robustness of the developed green method by applying 2^5-2 Res III 2- level fractional factorial design (FFD). Conclusion: An extensive stress degradation study along with degradation kinetics were performed and probable degradation pathways were predicted.

Key words: Lenalidomide, Green analytical chemistry, Quality by Design, Degradation kinetics, LC-MS/MS.
