Applications Isotope labelled 2-Imidazolidinethione (I350300) 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 transfer (1). 2-Imidazolidinethione is also a corrosion inhibitor (2) due to the adsorption of the mol. species.
