일반 설명
Trichloroacetic anhydride is reported to be an efficient derivatization reagent, since it produces stable derivatives having both a higher mass fragmentation pattern and lesser volatility than derivatives of trifluoroacetic anhydride (TFAA) or heptafluorobutyric anhydride (HFBA). The interaction of thymidine 5′-phosphate with trichloroacetic anhydride in dimethylformamide and acetonitrile in the presence of tertiary amines hs been studied.
애플리케이션
Trichloroacetic anhydride may be used as derivatization reagent for the following studies:
- Simultaneous analysis of amphetamine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA or Ecstasy) in urine samples by solid-phase extraction, derivatization and gas chromatography/mass spectrometry.
- Analysis of halogenated amphetamines in brain tissue from rats by gas chromatography with electron-capture detection (GC-ECD).
- Quantitative determination of the metabolites of l-alpha-acetylmethadol (LAAM), such as noracetylmethadol, dinoracetylmethadol, methadol and normethadol by electron capture gas-liquid chromatography.

p-Chloro-alpha-fluoromethylphenylethylamine (fluoro-p-chloroamphetamine) (FpCA) has been shown in acute studies to be a less potent depletor of the neurotransmitter amine 5-hydroxytryptamine (5-HT) in brain than is p-chloroamphetamine (pCA). Gas chromatographic assay procedures for FpCA and PCA have been developed in our

An analytical procedure for methamphetamine and amphetamine has been developed using 4-carbethoxyhexafluorobutyryl chloride. This derivatizing reagent has all the previously reported advantages of trichloroacetic anhydride (TCAA) in that it produces stable derivatives having both a higher mass fragmentation pattern and

A rapid and effective solid-phase extraction procedure using Bond Elute Certify bonded silica sorbent cartridges was adopted to extract amphetamine, methamphetamine, and 3,4-methylenedioxymethamphetamine (MDMA or Ecstasy) from urine samples. The extract was derivatized with trichloroacetic anhydride prior to gas chromatography/mass

Six reagents-trichloroacetyl chloride, trichloroacetic anhydride, pentafluorobenzoyl chloride, heptafluorobutyryl chloride, heptafluorobutyric anhydride, and trifluoroacetic anhydride- were evaluated as potential derivatizing reagents for quantitating the metabolites of l-alpha-acetylmethadol (LAAM) -noracetylmethadol, dinoracetylmethadol, methadol, and normethadol-by electron capture gas-liquid chromatography. All of the reagents

The interaction of thymidine 5'-phosphate with trichloroacetic anhydride, trichloroacetyl chloride, and tribromoacetyl bromide was studied in dimethylformamide and acetonitrile in the presence of tertiary amines. The first two reactions gave the mixed anhydride of trichloroacetic and thymidylic acids (acyl phosphate)
