Ethyl chloroformate is used as derivatization reagent to investigate stereochemical conversion of chiral non-steroidal anti-inflammatory drugs during derivatization reaction. It is also used with ammonia and cyanuric chloride to convert carboxylic acids to nitriles. It is used to develop flexible template strategy for the generation of nanometer-scale templates via dip-pen nanolithography.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
