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

Features and Benefits

  • 99.998% trace metals basis Ammonium chloride is essential in analytical chemistry as it prevents interference from impurities, ensuring accurate results, consistent reproducibility, enhanced signal clarity, and improved calibration.
  • Ammonium chloride (99.998% trace metals basis) is used in pharmaceuticals as a buffering agent and synthetic precursor, ensuring safety and efficacy while minimizing adverse reactions due to low impurity levels.
  • High purity NH₄Cl is used as an electrolyte in specific battery systems, improving ionic conductivity and enhancing overall battery performance.
