Phosphorus derivatives are a large and important group of chemicals widely used across many industries because of their unique reactivity and functional properties.

In agriculture, derivatives of Phosphoric Acid are the backbone of phosphate fertilizers such as Diammonium Phosphate and Monoammonium Phosphate, while organophosphorus compounds like Glyphosate, Malathion, and Chlorpyriphos are used as herbicides and insecticides.

In the detergent and cleaning industry, phosphate salts such as Sodium Tripolyphosphate and Sodium Hexametaphosphate act as water softeners and detergent builders.

In water treatment, phosphonate derivatives like HEDP and ATMP are used for scale and corrosion inhibition.

In plastics and fire safety, compounds such as Triphenyl Phosphate and Triethyl Phosphate function as flame retardants and plasticizers.

In pharmaceuticals and food, salts of sodium and calcium phosphate are used in IV fluids, tablets, baking powders, meat processing, and soft drinks (again based on Phosphoric Acid).

In metal treatment, Zinc Phosphate and Manganese Phosphate are applied as anti-corrosion coatings.

In batteries and electronics, Lithium Iron Phosphate is a key lithium-ion battery cathode material.

Finally, in matches and pyrotechnics, Red Phosphorus and Phosphorus Pentasulfide are essential ingredients.

Overall, phosphorus derivatives are critical to fertilizers, agrochemicals, detergents, water treatment, plastics, pharmaceuticals, food processing, metal protection, batteries, and pyrotechnics.
