Sodium azide (NaN3) is a colorless crystalline solid and is readily soluble in water. Sodium azide is a common preservative of samples and stock solutions in laboratories and a useful reagent in synthetic work. No SOP is required if a lab has ONLY pre-made kits where sodium azide is present as a preservative at 1% concentration or less.
