Prolan [Bis (p-chlorophenyl)-2-nitropropane] 
Sublethal doses of prolan were metabolized to unidentified compounds. 
In addition to unchanged prolan, an acidic metabolite, possibly bis (p-chloro- 
phenyl) pyruvic acid, has been isolated from the excreta of houseflies. UV and 
I.R. absorption and chemical tests showed that the NO», group had been lost 
and that a >C=O was present. It has been shown that this is not DDA (1142, 
1145).
