Impurities in Melphalan are controlled through strict quality control measures during the drug manufacturing process. Good Manufacturing Practices (GMP) ensure they are minimized and meet regulatory standards. Additionally, stability studies assess impurity formation over the drug's shelf life.

Research on impurities in Melphalan is an ongoing process. Scientists and pharmaceutical companies continue to explore and develop improved analytical techniques, manufacturing processes, and impurity control strategies to enhance the quality and safety of Melphalan and other medications.

Water or Methanol is the solvent used when analyzing most impurities in Melphalan.

Melphalan impurities should be stored, at a controlled room temperature, usually between 2-8 °C.
