General description
五氟苄基溴（PFB-Br）是一种衍生试剂。 过量的试剂可通过与氨基苯酚反应除去。它是一种烷基化试剂，适用于电子捕获检测器（ECD）检测。 同时也可作为催泪剂。
Application
它被用于通过负离子化学电离-气相色谱/质谱（NICI-GC / MS）分析D2 / E2-异前列腺素。在使用NICI-GC / MS测定脂肪酸的过程中，可以使用PFG-Br和二异丙基乙胺将脂肪酸转化为五氟苄基酯。
Other Notes
五氟苄酯试剂。

Previous studies reveal that supplementation of human diets with gamma-linolenic acid (GLA) reduces the generation of lipid mediators of inflammation and attenuates clinical symptoms of chronic inflammatory disorders such as rheumatoid arthritis. However, we have shown that supplementation with this

We recently reported the discovery that a series of novel prostaglandin (PG)F2-like compounds (F2-isoprostanes) are produced in vivo independent of the cyclooxygenase as products of free radical-catalyzed lipid peroxidation. F2-isoprostanes are initially formed in situ from arachidonic acid esterified to

A highly sensitive gas-liquid chromatographic method with electron capture detection of clonidine in plasma is described. The alkaline samples (100-200mul) are extracted into cyclohexane-butanol (9:1), re-extracted into 0.1 N sulphuric acid, made alkaline and back-extracted into cyclohexane-butanol. The pentafluorobenzyl derivatives
