    —— Product Detail ——


    Product Overview

    Ammonium phosphate dibasic (diammonium phosphate) is an inorganic compound with the molecular formula (NH₄)₂HPO₄ and a molecular weight of 132.06 g/mol. This white crystalline powder is a widely used source of phosphorus and nitrogen in fertilizers, as a buffer component in biochemical applications, and as a reagent in analytical chemistry. Its good solubility and buffering capacity make it valuable in various industrial and research applications, including in the preparation of buffer solutions for biological and analytical chemistry.

    Synthetic Process

    Ammonium phosphate dibasic is synthesized through the following routes:

    • Reaction of phosphoric acid with ammonium hydroxide: Phosphoric acid is neutralized with ammonium hydroxide to form ammonium phosphate dibasic.

    • Purification: The crude product is purified by recrystallization from water.

    Mechanism of Action / Application Principles

    • Fertilizer: Provides phosphorus and nitrogen nutrients for plant growth.

    • Buffer Solution: Used as a component in buffer systems for biochemical applications.

    • Analytical Reagent: Used in analytical chemistry for various determinations.
