1,3,5-Trinitrobenzene is one of three isomers of trinitrobenzene with the formula C6H3(NO2)3. A pale yellow solid, the compound is highly explosive.[2]

Synthesis and reactions

1,3,5-Trinitrobenzene is produced by decarboxylation of 2,4,6-trinitrobenzoic acid.[2][3]

1,3,5-Trinitrobenzene forms charge-transfer complexes with electron-rich arenes.

Reduction of 1,3,5-trinitrobenzene gives 1,3,5-triaminobenzene, a precursor to phloroglucinol.[4]

Uses and applications

Trinitrobenzene is more explosive than TNT, but more expensive.[2] It is primarily used as a high explosive compound for commercial mining and military applications. It has also been used as a narrow-range pH indicator, an agent to vulcanize natural rubber, and a mediating agent to mediate the synthesis of other explosive compounds.[5]
