Etorphine might be a possibility.  It is used primarily to anesthetize wild life.  Four mg will immobilize a 5000 kg elephant.  Its properties were discovered when a lab worker stirred the morning tea with a contaminated rod and nearly killed the workers(http://www.chm.bris.ac.uk/motm/etorphine/etorphinej.htm).  My daughter was trained to use it.  They were told that if they came in contact with it they should immediately inject the antidote right through their clothing.

I need the collective wisdom of the group…

I’m trying to think of any chemical that is soluble in benzene and has NO significant hazardous characteristics other than toxicity (i.e., not flammable, corrosive, water-reactive, etc.).  However, the more toxic it is, the better…

I do not want the actual chemical – just the name.  I’m trying to create a hypothetical “what-if” scenario for an upcoming discussion about responding to chemical spills in a laboratory.

If you have any suggestions, please reply direct to stevemclean**At_Symbol_Here**byu.edu

Thanks,

SJM
