We were successful in getting it from Aldrich: I do not know whether it is still available from the other three sources mentioned. Thanks to those who took the time to respond. "TEDION (2-4-4'-5-tetrachlorodiphenyl sulfone 95%) from : Chemical Dynamics Corporation, Hadley Road, P.O. Box 395, South Plainfield, New Jersey 07080.......Although I do not remember the exact price, a 50 gm bottle cost somewhere around $20." "Chem Service, Inc., PO Box 3108, West Chester, PA 19381-3108; 215-692-3026; Fax 215-692-8729: 1 gram = $36.70 and 10g = 251.20." "Allbright & Wilson, Midox Ltd, Glaston Park, Glaston, Oakham, Leicestershire, LE15 9BX. Tel 057 282 2561..... used in UK agriculture to control red spider mites.... The smallest amount they could supply was 5 litres as an emulsion of 8% tetradifon in 70% xylene." "Aldrich, catalog number S42834-5, and note on the order that this is an "ABC item." These items are kept in small amounts and are not in the catalog. The price was $35 for 5 grams." Aloha, Terry Lyttle ------- .
