As oligo synthesis involves moisture-sensitive reactions, it is optimal to use dehydrated solvents. Fujifilm Wako can supply anhydrous grade acetonitrile with minimum water content. Also, we have considerable experience in supplying not only small-volume packaging but also canister cans convenient for large-volume synthesis. Our acetonitrile has a proven track record for both laboratory scale and commercial scale synthesis and thus our product can be used with confidence.
