Diethylthiourea, a thiourea derivative, is used mainly as a rubber chemical, particularly in solid neoprene products.

N,N′-Diethylthiourea can be used as a reactant to prepare:

3,5-Diethyltetrahydro-4-thioxo-1,3,5-triazine-1(2H)-propanoic acid by condensation reaction with formaldehyde and β-alanine.
Methyl 3-ethyl-2-(ethylimino)-3,4-dihydro-4-oxo-2H-1,3-thiazine-6-carboxylate by one-pot reaction with dimethyl acetylenedicarboxylate in the presence of triphenylphosphine catalyst.
2-(Ethylimino)-3-ethyl-thiazolidin-4-one by cyclization reaction with 2-chloroacetic acid.
3-Ethyl-2-(ethylimino)-4-oxo-5-thiazolidineacetamide by condensation reaction with maleimides via Michael-type reaction.
