Copperphytate is a copper compound that is used as a fertilizer. It consists of copper(II) phosphate and has been shown to be an effective growth regulator for plants. Copperphytate also inhibits the production of pro-inflammatory cytokines, such as epidermal growth factor, and other inflammatory mediators. Copperphytate has been synthesized using quinoline derivatives to cross-link the phosphate groups with the copper ions, which form a stable complex. The synthesis of copperphytate can be achieved by reacting fluorine with molybdenum and then adding it to protein solutions. This reaction produces a blue precipitate that contains copper ions and phosphate groups. The chemical stability of copperphytate makes it an ideal agent for use in agriculture and horticulture.
