Some chemical formulations require refrigeration or freezer storageto slow down reactions among the components. Other standards requiresonication prior to use because they are near their saturation for theparticular formulation. It is imperative that these conditions are followed toensure the chemical reference standard will be at the stated concentration.1,3-Dimethyl-2-nitrobenzenePerylene-d 12TriphenylphosphateTel. 800-442-5290 / 203-786-5290 • Fax 203-786-5287 • Web AccuStandard.com 173
