Description

Trichloromethyl chloroformate is used as a reagent in the synthesis of organic compounds. It serves as a source of phosgene used in some laboratory preparations. Also, it is used as a reactant for the synthesis of cyclic carbamimidates, N-alkenyl and cycloalkyl carbamates and prostate-specific membrane antigen-targeted anticancer prodrugs. In addition, it is involved in the preparation of an erythromycin A derivatives and antibody-drug conjugates. It is utilized in the conversion of amines, carboxylic acids, formamides in to isocyanates, acid chlorides and isocyanides respectively.

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.
