Bits & Pieces

The "Bits & Pieces" section is intended for random snippets of information which don't fit
easily elsewhere and/or which have been newly added, but not yet carefully categorized.


  • Why the name "Dragonfly"?
    Some features of the chemical structure of Bromo-Dragonfly -- two furanyl rings with double bonds and an amphetamine arm -- suggest the appearance of a winged creature like a dragonfly.

    The name comes from the lab at Purdue where it was first synthesized as an agent for doing research into the structure and activity of the serotonin receptors in the brain. Researchers had designed a related chemical that they had been calling a "fly" because of the two furanyl rings attached to the benzene ring. Upon discovery that changing the bonds on the furanyl rings increased the potency substantially over the original "fly" compounds, the new style of compounds were dubbed "dragonfly" compounds.

  • Dragonfly / Fly indicates the 3-carbon amphetamine-style "tail"
    If one were to look at the Fly compounds as a modified phenethylamine or amphetamine structure, the "fly" names refer to the amphetamine family, with the 3-carbon side chain. The phenethylamine versions are sometimes referred to using the Shulgin notation of "2C" (for 2-carbon) to indicate that the "fly-tail" lacks the amphetamine carbon. See Chem Compare to compare the tail and note the double bonds on the furanyl rings that differentiate the "dragonfly" from the "fly" compounds.

  • Two Batches with Very Different Dosages Sold
    There appear to be two batched of Bromo-Dragonfly being sold around the world as of Oct-Dec 2005. One batch appears to be strongly active below 500 micrograms (.5 mg) and the other seems to be being used between 1 and 1.5 mg. It is not yet known why this difference exists, although animal and human bioassay of material in research appears to suggest the lower activity level. Users are warned to be very careful when using grey market research chemicals.

  • R-Isomer More Active
    Although we have not confirmed this, we are told that the R-Isomer of Bromo-Dragonfly is the more psychoactive isomer.
