Used primarily in research settings for studying immunomodulatory and anticancer mechanisms. It serves as a metabolite of lenalidomide, helping scientists understand drug metabolism and activity in diseases like multiple myeloma and other hematological cancers. Its structure allows investigation into how acetylated forms of drugs influence bioavailability, stability, and therapeutic effectiveness. Also utilized in analytical studies to develop sensitive detection methods in biological samples, supporting pharmacokinetic and metabolic profiling.
