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

Association of cholinesterase with β-amyloid plaques and tau neurofibrillary tangles in Alzheimer's disease offers an opportunity to detect disease pathology during life. Achieving this requires development of radiolabelled cholinesterase ligands with high enzyme affinity. Various fluorinated acetophenone derivatives bind to
