Urea is a nitrogenous compound containing a carbonyl group attached to two amine groups with osmotic diuretic activity. In vivo, urea is formed in the liver via the urea cycle from ammonia and is the final end product of protein metabolism. Administration of urea elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain, cerebrospinal fluid and eye, into interstitial fluid and plasma, thereby decreasing pressure in those tissues and increasing urine outflow.

Sodium nitrate is the raw material for the manufacture of potassium nitrate, mine explosives, picric acid, dyes, etc. Nitrifiers for the manufacture of dye intermediates. The glass industry is used as antifoam, decolorizer, clarifier and oxidative fluxing agent for the production of various glasses and their products. The enamel industry uses as oxidants and fluxes for the formulation of enamel powders. The mechanical industry is used as a metal cleaner and also in the formulation of ferrous bluing agents. Metallurgical industry is used as steelmaking and aluminum alloy thermal treatment agents. Light industry used as a fuel aid in the manufacture of cigarettes. The pharmaceutical industry uses culture media for penicillin. Fertilizers the industry is used as a rapid acting fertilizer suitable for acidic soils, especially for root tuber crops such as sugar beets and radishs and so on. Also used as decolorizing agent for molten carnitine. High purity analytical reagents, spectroscopic reagents, oxidizing agents and also used in dye synthesis and the manufacture of explosives and fireworks. Nitrates all have early and strong effects, especially at low temperatures and negative temperatures, acting as early and antifreezing agents. Used in toothpaste as a corrosion inhibitor, desensitizing agent, to prevent dentin sensitization. Sodium nitrate is mainly used in the field of water treatment as a corrosion inhibitor, boiler metal embrittlement. In addition, there is a wide range of uses in other areas. The addition of sodium nitrate inside the low pressure boiler system inhibits the corrosion of metals on the water side and prevents the embrittlement of metallic materials. Sodium nitrate, when used as an inhibitor of metal embrittlement, needs to be used in complex with sodium hydroxide and maintained in a certain ratio. Plating grade or chemically pure sodium nitrate can be used for plating black chromium additions, also in black chromium plating electrolyte, as well as in the low chromate passivation of the zinc coated layer, and in the oxidation solutions of zinc, magnesium and magnesium alloys.

Sodium tripolyphosphate is a white powder crystal with good fluidity. It is easily soluble in water and its aqueous solution is alkaline. Sodium tripolyphosphate is commonly used in food as water retention agent, quality improver, pH regulator and metal chelator. For example, sodium tripolyphosphate can increase the tenderness of meat, and can also be used as food improver of fish products and clarifier of drinks.

HEA is mainly applied in the production of thermosetting coating, cementing compound, polycarboxylate superplasticizer and synthetic resin copolymer modifier.

Trichloro-s-triazinetrione, dry appears as a white slightly hygroscopic crystalline powder or lump solid with a mild chlorine-like odor. Said to have 85 percent available chlorine. Decomposes at 225°C. Moderately toxic by ingestion. May irritate skin and eyes. Active ingredient in household dry bleaches. Used in swimming pools as a disinfectant .
