A lab tech noticed a statement on a Dichloromethane bottle that said "store under an inert gas". He would like to know if this is a safety recommendation or designed to maintain the quality of the chemical by avoiding exposure to environmental gases. From what I can find, it appears to be the latter, but I thought I would ask DCHAS-L to see if anyone knows of a safety reason for this recommendation.
Thanks for any help with this.
