Colour of Methylammonium Iodide (MAI) in Isopropanol (IPA, 99.7%) turned slightly green after storing some time?

19 April 2020 1 8K Report

Has anyone observed the changes of colour of MAI in IPA to slightly green-ish after storing some time? I might have to prepare fresh solution again if this is abnormal. Could anyone verified the change in solution colour?

Thank you.

Thank you very much! I was wondering what happened to my MAI/IPA solution prepared before the 3 months lockdown.
