General description
Phosphorus pentoxide (P2O5) is a commonly used drying agent. It is a component of Eatons reagent, which is commonly used as a catalyst for dehydration reactions.
Application
Phosphorus pentoxide may be used in the synthesis of the following:
- Hydroxyapatite (HA) sub-micron fibers.
- Fluorescent carbon nanoparticles (FCNPs).
- Bistetramethylammonium (TMA) hydrogencyclotriphosphate and rubidium cyclotetraphosphate using dimethyl sulfoxide as a solvent at low temperature condition.
- Ethylene glycol methacrylate phosphate (EGMP), a UV-reactive phosphonic acid.
Features and Benefits
Meets A.C.S. reagent specifications.
