Sigma Aldrich has a SDS that says, "Heat sensitive. Store under inert gas" I don't agree with that statement but thought you should know about the ref. My experience says the inert gas recommendation is to prevent it from evaporating while storing. A liquid seal cap should negate the need for the inert gas too I think.

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.
