Application

Ammonium dihydrogenphosphate can be used:
  • As a precursor to fabricate cathode materials for Li-ion batteries to enhance cyclic performance.
  • As an electrolyte additive in rechargeable batteries to enhance the ionic conductivity or to reduce the risk of side reactions within the electrolyte.
  • To fabricate flame-retardant polymer composites.

General description

Ammonium dihydrogenphosphate is a white crystalline solid widely applied in rechargeable batteries, non-linear optics, and fire-retardant coatings. It is insoluble in ethanol and acetone.

Improvements to phosphopeptide enrichment protocols employing titanium dioxide (TiO2) are described and applied to identification of phosphorylation sites on recombinant human cyclin-dependent kinase 2 (CDK2). Titanium dioxide binds phosphopeptides under acidic conditions, and they can be eluted under basic conditions.
