一般描述
硫酸铵是一种用途广泛的无机盐，通常用作农业肥料作为氮和硫源。它也被用作萃取剂来萃取金属，如铁、铬、铝和钙。此外，硫酸铵用于纯化血清或腹水中的抗体和沉淀或分离蛋白质。
应用
硫酸铵可作为钯催化芳基卤化物胺化反应的试剂在叔丁二氧化钠环境下生成芳胺。它还可以作为催化剂，用于喹唑啉-4(3H)-酮与伯胺的六甲基二氮杂烷介导反应，以合成 4-氨基喹唑啉。

In this study we examined the mechanism by which ammonium bicarbonate inhibits mycotoxigenic fungi. Elevated extracellular pH, alone, was not responsible for the antifungal activity. Although conidia of Penicillium griseofulvum and Fusarium graminearum had internal pH (pHi) values as high
