4N (99.99%) Ethyl Methyl Carbonate EMC (C4H8O3) for Battery Research 

Ethyl Methyl Carbonate, EMC, (C4H8O3) is a low-viscosity solvent produced through the esterification of chloroform-ate and ethanol. It features active, reactive groups such as methyl, ethyl and carbonyl, permitting reactions with alcohols, phenols, amines and esters for using in fine synthesis intermediates. It is widely used as electrolyte solvent for battery research.
