一般說明

据报道,三氯乙酸酐是一种有效的衍生化试剂,因为与三氟乙酸酐(TFAA)或七氟丁酸酐(HFBA)的衍生物相比,三氯乙酸酐可产生质量分数更高、挥发性更低的稳定衍生物。 已经研究了在叔胺存在下,胸苷5′-磷酸与三氯乙酸酐在二甲基甲酰胺和乙腈中的相互作用。

應用

三氯乙酸酐可在以下研究中用作衍生化试剂:
  • 通过固相萃取、衍生化和气相色谱/质谱法同时分析尿液样品中的苯丙胺、甲基苯丙胺和3,4-亚甲基二氧基甲基苯丙胺(MDMA或Ecstasy)。
  • 通过气相色谱-电子捕获检测法(GC-ECD)分析大鼠脑组织中的卤代苯丙胺。
  • 通过电子捕获气-液相色谱法定量检测l-α-醋美沙朵(LAAM)的代谢物,如去甲醋美沙朵、二去甲醋美沙朵、美沙朵和去甲美沙朵。

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)
