Dear Chemweb members: I'm not sure if this is the right listserv for this question, but here it goes (if you know of a more appropriate listserv please let me know). I have some laboratory analytical data that shows the presence of thiobispropane and methylthiopropane in a soil sample. I can't find any information about these compounds. Does anyone know what these compounds are and what they're used for? Many thanks in advance, John ps 1,1'- thiobispropane cross references with propyl sulfide in the Merck Index but I have thiobispropane (without the 1,1'-). John W.
