TOXAPHENE ANALYSIS: I am interested in the quantitation of TOXAPHENE, a pesticide produced by the extensive chorination of camphene. This pesticide, which is now banned in the USA and CANADA, is a very complex mixture of well over 400 isomers of Cl2-Cl10 chlorobornane isomers. I am interested in obtaining samples of the three most toxic components of the mixture. They are: Toxicant A-1: 2,2,5-endo 6-exo 8,8,9,10-octachlorobornane Toxicant A-2: 2,2,5-endo 6-exo 8,9,9,10-octachlorobornane Toxicant B : 2,2,5-endo 6-exo 8,9,10-heptachrorobornane At the present I would only require enough for analytical standards (5-10 mg), but am also going to try to scale up and produce 500mg-1 gm quantities. I would like to hear from anyone who would have some samples of the above compounds or have protocols for their isolation. *********************************************************************** Paul Andrews Bureau of Chemical Safety Food Research Divsion Health and Welfare Canada Tunney's Pasture, Ottawa, Ontario, Canada PANDREWS@HPB.HWC.CA 1-613-957-0951 -------
