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.
