应用
磷酸二氢铵可用于研究优化试剂、蛋白质结构分析、蛋白质组学、X 射线晶体学和生物缓冲液。磷酸二氢铵已被用于开发一种简单的高效液相色谱方法,用于测定尿液中的 N1-烷基烟酰胺,包括 C1C5 烷基衍生物。磷酸二氢铵还被用于开发一种将高效液相色谱分析与紫外检测(254 nm)相结合的方法,用于测定人血浆中咪达唑仑及其两种羟基化代谢物。

A simple high-performance liquid chromatographic method has been developed for determining N1-alkylnicotinamides, including C1-C5 alkyl derivatives, in urine. N1-Alkylnicotinamides were reacted with acetophenone in strong alkali medium at 0 degrees C and then formic acid was added. The reaction mixture
