laboratory
Diammonium hydrogen phosphate can be used in the laboratory to prepare buffer solutions and culture media, and is a nutrient for yeast cultivation. It can also be used as an analytical reagent for precipitation and pH buffer of magnesium, zinc, nickel, uranium, etc. It can be used as a supporting electrolyte in electrochemical analysis.
food industry
Diammonium hydrogen phosphate is used in the food industry as a food leavening agent, dough conditioner, buffer, yeast feed, bread improver, and fermentation assistant for brewing. It can also be used for refining sugar.
Agriculture and animal husbandry
Diammonium hydrogen phosphate is a compound fertilizer containing both nitrogen and phosphorus nutrients. It is a high concentration quick acting fertilizer with less solid matter after dissolution. It is suitable for various crops and soils, especially for crops that love nitrogen and need phosphorus. It can be used as a base fertilizer or topdressing. When applied on acidic soil, it can reduce the fixation of iron and aluminum on phosphorus, maintain high phosphorus availability, and should be applied deeply. It can be used as a feed additive for ruminants in animal husbandry.
Chemical production
Diammonium hydrogen phosphate is used for flame retardant treatment of fabrics, paper, wood, and plant fibers, as well as impregnation treatment of lamp wick to increase its durability and self extinguishing treatment after ignition of matches. It can be used as a dry powder fire extinguishing agent and phosphorus in fluorescent lamps. Can be used as welding flux for tin, copper, bronze, and zinc. It is also used in fields such as printing plate making, electronic tube manufacturing, and ceramic and enamel industries. Used for chrome dyeing of wool fabrics in the printing and dyeing industry.
water treatment
Diammonium hydrogen phosphate is mainly used as a corrosion inhibitor in the field of water treatment and as a bacterial nutrient in the biochemical treatment of wastewater. It is also used as a water softener component in boiler water.
