Description

Description

Applications
Triphosgene is used as a carbonylating agent for aza-peptide synthesis. It reacts with several alfa-amino acids to give the corresponding N-carboxyanhydrides. It is involved in the preparation of the esterification coupling reagent, di-2-thienyl carbonate from 2(5H)-thiophenone. Further, it is used as a reagent in organic synthesis and converts an amino group into isocyanate. In addition to this, it is employed in the preparation of 2-chloronicotinaldehydes through cyclization of the corresponding enamides. It is considered as a useful substitute for phosgene.

Solubility
Soluble in ether, ethanol, tetrahydrofuran, benzene, cyclohexane, chloroform, hexane, carbon tetrachloride, dichloromethane and chlorobenzene. Insoluble in water.

Notes
Moisture sensitive. Store in a cool place. Incompatible with oxidizing agents.
