Description and Uses

Ethylenethiourea, a thiourea derivative, is a rubber chemical. It has caused contact dermatitis mainly in rubber workers.

2-Imidazolidinethione is a pesticide used in production of fruits and vegetables. It is also used as a new contrast agent for MRI studies based on proton chemical exchange dependent saturation transfe r. 2-Imidazolidinethione is also a corrosion inhibitor due to the adsorption of the mol. species.
