Explodes when heated. Explosive or violent reactions with Lewis acids [e.g., aluminum chloride (explosive); sulfuric acid (violent)]. When heated to decomposition it emits toxic fumes of NO_x. See also AZIDES
.A protective blast shield is needed during purification and handling. Distillation temperatures should be as low a possible. Organic Syntheses recommends 5mm Hg to give a boiling point of ''66–68 °C/21 mm. with a bath temperature of 70–75 °C.'' The pure substance may be stored in the dark, cold, and even then the shelf-life is only weeks.
