Application
四甲基氢氧化铵五水合物可用于全硅分子筛silicalite-1晶种合成。
四甲基氢氧化铵五水合物在一项研究中通过一步气体色谱，评估 Pseudomnas菌株。 它还被用来研究固体状态金属氢化物电池，氢氧化镍金属氢化物和二氧化锰金属氢化物。
General description
四甲基氢氧化铵(TMAOH)是一种离子对试剂，通常在分析化学中使用。可用于海洋化合物的薄层色谱-热解-气相色谱-质谱(TLC-pyrolysis-GC/MS) 和热解吸/毛细管气相色谱/电感耦合等离子体质谱分析。四甲基氢氧化铵可用于无机阴离子的毛细管区带电泳分离。研究报道，TMAOH可促进寡核苷酸链的复性。四甲基氢氧化铵适于合成某些有机和无机化合物，例如卤化乙烯和四甲基氢氧化铵二硫代羧酸盐。TMAOH可作为氧化铁纳米粒子制备中的磁共振成像造影剂。
