I don't remember why/when I drew this, but could anyone tell me if it is something?  To me it kind of looks like a weird nitroglycerin molecule with an extra carbon and with nitrite instead of nitrate.

-NO₂ could have been a nitrite (not always written as -ONO), but the drawing at right hand shows nitro groups.

The drawn compound resembles some explosives but not the best known ones, which are more often nitrates or nitramines. Two double bonds make it approximately oxygen-balanced, but it can be sensitive to sunlight, ozone, NO_x in the air.

Or has it completely different uses? A detector or scavenger for some gas? A precursor to a tetranitrobenzene?
