| Hazard Information | Back Directory | [Uses]
N-Ethylthiourea was used in the preparation of Re (III) complexes, which are precursors for the new rhenium complexes, potentially useful in nuclear medicine. It was also used in two-step protocol for the first chemoselective cleavage of 2-hydroxy acid amides | [Definition]
ChEBI: N-ethylthiourea is a member of the class of thioureas that is thiourea in which one of the hydrogens is replaced by an ethyl group. It is functionally related to a thiourea. | [General Description]
N-Ethylthiourea forms adduct with silver halides and their single crystal X-ray structural and spectroscopic characterizations are described. | [reaction suitability]
reagent type: catalyst
reagent type: chelator | [Biological Activity]
Potent, selective and reversible inhibitor of isoform II NO synthase (IC 50 = 13 nM; approximately 20- and 30-fold selective over isoforms I and III respectively). | [Purification Methods]
Crystallise the thiourea from EtOH, MeOH or ether. [Beilstein 4 IV 374.] |
