         Dear Russ,
         Is an organic compound? If it is, I think that PBT Profiler
software can help. There you can look information using the chemical
structure of the compound. I hope it can help.
         Have a nice day,

Subject: [DCHAS-L] Research chemicals of unknown toxicity
         Dear fellow ACS Div-CHAS members,
         I'm looking for advice on what you tell your people about working
         chemicals of unknown toxicity.
         In my current case, I have a researcher who will administer a
         she is getting from a colleague at the EPA to mice. Some ata I have
         similar compounds show those chemical to be 'not very toxic' but I
         not find any information about this stuff.
         I only half-jokingly suggested she obtain an MSDS from the EPA as
         are the supplier.
         I'm inclined to tell them to treat the material as highly toxic and
         collect the metabolites found in the mouse bedding/feces/urine and
         handle as hazardous waste. At least until they have more
         about the hazards.
         Do you agree? Do you have any particular guidance you would care to
         Thanks in advance!
