General description
Reinecke盐[四金刚烷二胺铬酸铵（III）]是一种铵盐。它可通过形成reineckate复合物而参与到存在于酸性组织提取物中的组蛋白和碱性化合物的定量沉淀。
Application
Reinecke盐可作为沉淀试剂用于分离延胡索干粉中的季铵生物碱（QAA）。可通过MALDI-MS（基质辅助激光解吸电离-质谱）对这些QAA进行定量分析。它可用于制造大量的Meldola蓝磷酸锆-Reinecke盐丝网印刷电极（bMBZrPRs-SPEs）。
汞的着色剂和沉淀剂。 伯胺和仲胺以及某些氨基酸的沉淀剂。

Three accurate, rapid and simple atomic absorption spectrometric, conductometric and colorimetric methods were developed for the determination of norfloxacin (NRF), ciprofloxacin (CIP), ofloxacin (OFL) and enrofloxacin (ENF). The proposed methods depend upon the reaction of ammonium reineckate with the studied
