NLT 80% of batch volume ethanol was transferred into a manufacturing vessel.

Propylene glycol was added to a vessel containing ethanol. Melphalan was added to the above mixture. Check the pH of the sample and if required adjust the pH to 3.5-5.5 using 0.1N NaOH/0.1N HCL. Final batch volume was made up using ethanol. The obtained solution was filtered and filled in vials followed by capping and sealing. The formulation was tested for stability at 2-8° C. for a period of 1 Month. Stability data is summarized 13A.
