Propylenethiourea (4-methylimidazolidine-2-thione) is the major
breakdown product of Propineb, a fungicide of the
propylenebisditiocarbamate group.
The degradation pattern of Propineb is analagous to those of
ethylenebisdithiocarmabates which give ethylenethiourea as the principal
metabolite. This compound has been reported to possess a carcinogenic
activity. [Continues.
