Description

Application

• 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.

Packaging
