Use specially manufactured and packaged Thermo Scientific™ Silylation Grade Solvents to meet the exacting needs of silylation and other sensitive derivatization reactions. They are purified, dried, and packaged under nitrogen in convenient Thermo Scientific™ Hypo-Vial™ Sample Storage Vials, and are supplied with elastomer septa to enable immediate access to the sample without exposure to moisture and oxygen. Use polar solvents (acetonitrile, dimethylformamide, dimethylsulfoxide, pyridine, tetrahyrdrofuran) to facilitate reactions; nonpolar organic solvents may be used but will not accelerate the rate of reaction.
