Ammonium oxalate monohydrate has diverse applications, including being a buffering reagent, a dispersant, and an anticoagulant. It’s also used in analytical chemistry for detecting and determining various metals like calcium, lead, and fluoride. Additionally, it acts as a reducing agent in gold extraction and is a component in metal polishing fluids.

• Analytical Chemistry:

  Ammonium oxalate is a key reagent in various tests, particularly for detecting and quantifying metals like calcium, lead, fluoride, and rare earth metals. 
• Anticoagulant:

  It’s used to prevent blood from clotting, making it useful for preserving blood samples in test tubes. 
• Reducing Agent:

  It can act as a reducing agent, meaning it can donate electrons to other molecules, which is useful in various chemical processes, including gold extraction. 
• Buffering and Dispersing Agent:

  It can be used as a buffering reagent to maintain a stable pH in solutions and as a dispersant to keep particles suspended in a solution. 
• Metal Polishing:

  It’s a component of ferrous metal surface polishing fluid, contributing to the polishing process.
