--------------------------- HYDROWIN v2.00 Results ---------------------------

Hydrolyzable Function detected: Thiocarbamate

-C-S-C(=O)-N-C

The common thiocarbamate function hydrolyzes very slow at environmental

pHs with half-lives greater than 100 days.

Validity criteria fulfilled:
not specified
Conclusions:
The estimated half-life of 1,3-thiazolidine-2,4-dione was estimated to be > 100 d (at 25 deg C), indicating that it not hydrolysable.
