General description

Ethyl isocyanate undergoes trimerization at high temperature for the synthesis of Isocyanurates.

Application

Ethyl isocyanate may be used to generate thermoresponsiveness in polyglycidol via partial hydrophobic modification. The poly(glycidol-co-ethyl glycidyl carbamate) thus formed can undergo photocrosslinking in the presence of a photosensitizer to form thermoresponsive gels. It can also be used in the synthesis of 4,5,6,7-tetrahydrobenzo[1,2-d]thiazole-2,6-diamine derivatives that are potent DNA gyrase inhibitors.

Validation of a solvent-free sampler for the determination of low molecular weight aliphatic isocyanates under thermal degradation conditions.

M Boutin et al.

Journal of occupational and environmental hygiene, 2(9), 456-461 (2005-08-11)

During the thermal degradation of 1,6-hexamethylenediiso- cyanate-based (HDI) car paint, the eight most abundant isocyanates generated are isocyanic acid, methyl isocyanate, ethyl isocyanate, propyl isocyanate, butyl isocyanate, pentyl isocyanate, hexyl isocyanate, and 1,6-hexamethylenediisocyanate. For the first time, a method using

Ethyl 2-acrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate as well as its corresponding bis-derivatives, 5-10, with aliphatic linkers were synthesized, fully characterized, and tested as novel anticancer agents. The targeted compounds, 5-10, were obtained by the Knoevenagel condensation reactions of bis-o- or -p-aldehyde with a molar
