A new sensitive derivatization reagent for use in liquid chromatographic separation of hydroxyl compounds has been developed. A suitable reagent for this purpose, 4-dimethylamino-1-naphthoyl nitrile, was readily prepared from the corresponding acid chloride by the exchange reaction with trimethylsilyl cyanide. Condensation of a hydroxyl compound with the reagent was effected in the presence of triethylamine under the mild condition. The resulting ester was highly responsible for a fluorescence detector with a detection limit of 200 pg.
一种用于液相色谱分离羟基化合物的新型灵敏衍生试剂已经研制成功。4-dimethylamino-1-naphthoyl nitrile(4-二甲氨基-1-萘甲酰腈)是一种适用于此目的的试剂,通过与三甲基硅烷氰化物的交换反应,很容易从相应的酰氯中制备出来。在三乙胺存在的温和条件下,羟基化合物与试剂发生缩合反应。生成的酯对荧光检测器的作用很大,检测限为 200 pg。
