一般說明

Photolysis of the vapour of chlorodifluoroacetic anhydride has been studied over the range 19-201°C using 248nm radiation.

應用

Chlorodifluoroacetic anhydride has been used:
  • for dual element acetylation tagging derivatization of amines by using microwave sustained helium emission detector
  • as derivatization reagent in determination of estrone and 17β-estradiol in hair by GC-MS
