Safety & protection
Exposure Control and Personal Protection
TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].

Chemistry & industry
Uses & manufacturing
Applications
UsesEthyl cyanoformate is used as reagent in the preparation of N-substituted amindinoformic acid and ethyl-4-quinazoline -2-carboxylate.
UsesEthyl Cyanoformate (cas# 623-49-4) is a compound useful in organic synthesis.
UsesEthyl cyanoformate can be used as a cyanide source for the cyanation of:Activated olefins in the presence of a titanium catalyst.Carbonyl compounds catalyzed by 4-dimethylaminopyridine (DMAP) to yield corresponding cyanohydrin carbonates under metal-free and solvent-free conditions.Aldehydes and 2,2,2-trifluoroacetophenone catalyzed by N-heterocyclic carbene (NHC) to yield corresponding cyanohydrins ethyl carbonates.
