Talk:Methanesulfonic acid

Expiration date
Why does the Me-SO2-OH have an expiration date? What happens to it? Does it matter if we used sulfuric or methyl-sulfonic acid in water solution for hydrolisys purposes? Why do we need to use methyl sulfonic, if sulfuric will do the same job? —Preceding unsigned comment added by 74.247.199.50 (talk) 20:25, 8 April 2011 (UTC)
