The packaging environment is determined by the sensitivity of the material to light, oxidation, or atmospheric humidity, and by its toxicity.
Where appropriate, containers are filled in a glove box under inert gas and in conditions of controlled low residual humidity. The need usp reference standard catalogue store such standards under inert gas protection is indicated on the label.
