Hexanitrostilbene (HNS), also called JD-X, is an organic compound with the formula [(O2N)3C6H2CH]2.

It is slightly soluble (0.1 - 5 g/100 mL) in butyrolactone, DMF, DMSO, and N-methylpyrrolidone.

It is produced by oxidizing trinitrotoluene (TNT) with a solution of sodium hypochlorite.

[1] Because of its insensitivity but high explosive properties, HNS is used in space missions.

It was the main explosive fill in the seismic source generating mortar ammunition canisters used as part of the Apollo Lunar Active Seismic Experiments.
