  • Categories and Type Sodium dihydrogen phosphate is classified as an inorganic salt and belongs to the group of phosphates.
  • Uses and Mechanism of Action Sodium dihydrogen phosphate is a synthetic compound commonly used in various industrial applications, including tanning, boiler water treatment, compound fertilizer production, metal detergent formulation, pH buffering, and pigment precipitation.

    In the construction industry, it is used as an additive to magnesium phosphate cement (MPC) to modify the crystal structure of hydration products, thereby improving mechanical properties such as flexural and compressive strength.[1]
    In food processing, it is utilized in combination with ascorbic acid (Vc) to inhibit browning in yellow alkaline noodles by reducing the activity of polyphenol oxidase (PPO) and quinone content.[2]
    In the mining industry, it serves as an activator for dolomite in reverse flotation separation processes, enhancing the selective flotation of dolomite from magnesite ores.
  • Regulatory Status Sodium dihydrogen phosphate is generally recognized as safe (GRAS) by the FDA and is widely used in food processing.
  • Production Methods Sodium dihydrogen phosphate is produced through chemical synthesis methods. It's solubility in water and stability make it suitable for various industrial applications.
  • Analysis Method The effects of sodium dihydrogen phosphate on materials such as magnesium phosphate cement, yellow alkaline noodles, and mineral ores are analyzed using techniques such as X-ray diffraction (XRD), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR), pore structure determination, micromorphology analysis, energy spectrometry (EDS), X-ray photoelectron spectroscopy (XPS), zeta potential measurements, and density functional theory (DFT) calculations. These methods help elucidate the mechanisms underlying the compound's effects and interactions in different systems.
