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.

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.

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.
