4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo[5.5.0.0.0]-dodecane - which is most commonly and conveniently abbreviated TEX - is a dense (ρ = 1.985 g cm) nitramine high explosive, that derives from the very powerful and sensitive high explosive CL-20. Though related to CL-20 in that is shares the same cage structure TEX is more easily synthesized in good yield from cheap starting materials. Much unlike CL-20 TEX is friction insensitive, bears a low impact sensitivity and possesses a very low shock sensitivity and large critical diameter making it an interesting explosive filler for insensitive munitions. Its systematic name, 4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo[5.5.0.0.0]-dodecane derives from its tetracyclic structure which is depicted below.
