Application

Ammonium chloride (NH4Cl) is an ammonium salt which can be used for a variety of applications such as:
  • a catalyst for the one-pot synthesis of 3,4-dihydropyrimidin-2-(1H)-ones
  • a promoter in the multicomponent synthesis of pyrrolo[3,4-b]pyridine-5-one
  • a reagent to improve the hydrolysis rate of magnesium hydride for the generation of hydrogen
  • a reductant, which facilitates the recovery of metals that are utilized in lithium-ion batteries
