The name of this explosive is 3,3-diazido-2,4-dinitratopentane, and that is about all I know for this compound except it is very sensitive to friction and shock. It has been proposed as a propellant and as a percussion primer for caseless ammunition.

Prepare a nitrating solution by slowly adding 4.56 mL of 100% nitric acid with a dropper pipet to 10.68 mL of acetic anhydride in a small Erlenmeyer flask, and cool the solution to 0-5 C. While maintaining the temperature at 5-15 C, add 4.2 g of solid 3,3-diazido-2,4-pentanediol over a period of 20 minutes. Stir the mixture for 30 minutes, with a magnetic stirrer or by occasionally swirling the flask, after which time some crystallization should have occurred. Complete precipitation is achieved by drowning the mixture in an excess of ice water. The product is extracted with ethyl ether and recrystallized from hexane. The yield is about 85%. You will need a graduated cylinder for measuring liquids and a thermometer to monitor the temperature.
