General description

Octyl isocyanate was reported to inactivate serine proteinase, chymotrypsin.

Application

Octyl isocyanate was used to suppress side reactions such as backbiting or chain transfer reaction during polymerization reactions. It was also used in the synthesis of:
  • low molar mass organogelator containing 2-(2′-hydroxyphenyl)benzoxazole (HPB) unit with long alkyl chain
  • N-octylurea
  • N-cyclopropyl-N′-octylurea
