Aplicação

  • Ethyl chloroformate was used in the synthesis of nitrile oxides.
  • It was used as derivatization reagent to investigate stereochemical conversion of chiral non-steroidal anti-inflammatory drugs during derivatization reaction.
  • It was used to develop flexible template strategy for the generation of nanometer-scale templates via dip-pen nanolithography.
  • It was used as derivatization reagent in an enantiomeric analysis of amino acids by two-dimensional gas chromatography.
  • It was also used with ammonia and cyanuric chloride to convert carboxylic acids to nitriles.

A potential problem with chiral derivatization is the possibility of stereochemical conversion during the derivatization reaction. This possibility has been examined using the non-steroidal anti-inflammatory drugs ibuprofen, ketoprofen, etodolac and flurbiprofen.
