Most of the compounds that we offer are air-sensitive and are packaged accordingly. In order to prevent decomposition of these materials the Buyer should take all possible precautions to prevent exposing these materials to air and other contaminates. It is suggested that the Buyer transfer these materials while sealed inside the metal/foil bag into a dry box under an inert atmosphere (e.g. nitrogen gas with < 0.5 ppm O2 and H2O). It is also suggested that these materials be stored inside a refrigerator at temperatures of -10 °C to further prevent decomposition.
