During a lab inspection today, I noticed a bottle of extra pure Dimethylformamide in one of our labs that had a note on the manufacturers (Acros) label that says "use within 5 years of opening". A little Google searching doesn't seem to indicate the DMF is a peroxide former, so I wonder if anyone can shed some light on why this time limit is recommended?

The bottle was received in Jan 2011, so inquiring miles would like to know.

thanks for any insight on this.
