General description

1-Chloroethyl chloroformate is used as a selective dealkylating agent for tertiary amines.

Application

1-Chloroethyl chloroformate was used:
  • for N-demethylation reaction during determination of multiple drugs of abuse in biological fluids using capillary electrophoresis with native fluorescence and laser-induced fluorescence detection
  • as catalyst in chemoselective desilylation of silyl-protected alcohols
  • as reagent in N-demethylation of tertiary amines to produce drug metabolite reference material for forensic toxicological applications
  • as reagent to cleave benzhydryl groups from amines
