di-Ammonium Hydrogen Orthophosphate AR 500g
Codi-Ammonium Hydrogen Orthophosphate AR (Analytical Reagent) is a high-purity phosphate salt (( \(NH_{4}\) ) \({}_{2}\) \(HPO_{4}\) or \(NH_{4}H_{2}PO_{4}\) ).
It is widely used as a precision laboratory reagent, in pharmaceuticals, and for specialized industrial applications where strict purity and uniform composition are required.
Key Uses
Laboratory & Analytics: Functions as an analytical reagent, an excipient in pharmaceutical formulations, and a crucial buffer component for pH control.
Fermentation: Provides a vital nitrogen and phosphorus source for yeast cultures used in baking, brewing, and winemaking.
Fire Retardant: Used in flameproofing textiles, paper, wood, and vegetable fibers.
Soldering Flux: Acts as an active flux for joining metals like tin, copper, brass, and zinc by promoting proper flow and adhesion.
Agriculture & Food: Serves as an ingredient in specialty fertilizers, as well as a leavening agent and dough conditioner in baking.
Other Applications: Used in the production of dentifrices, corrosion inhibitors, impregnating lamp wicks, and as an afterglow preventative in matches.
