1,3,3-Trinitroazetidine

1,3,3-Trinitroazetidine (TNAZ) is an explosive heterocyclic compound that has been considered as a potential replacement for TNT because of its low melting point (101 °C) and good thermal stability (up to 240 °C). TNAZ was first synthesized by Archibald et al. in 1990.[3] Several synthesis routes are known, and bulk production of several hundred kilogram batches has been demonstrated at Los Alamos National Laboratory.[4][1][5]
