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

An efficient procedure is described for the determination of estrone and 17 beta-estradiol in hair by gas chromatography-mass spectrometry (GC-MS). The method involves alkyloxycarbonylation with isobutyl chloroformate (isoBCF) of phenolic hydroxy groups after alkaline digestion of hair samples. The resulting
