Quaternary ammonium cation - Wikipedia

They are used to make other organic chemicals including rubber vulacanization accelerators, pesticides, quaternary ammonium compounds, photographic chemicals, corrosion inhibitors, explosives, dyes and pharmaceuticals.

As with any highly active oxidizer, concentrated PAA can present a safety hazard.

Quaternary Ammonium Compounds (QACs or Quats)
Quaternary ammonium compounds are fairly complex chemicals in which nitrogen is bound to four organic groups.
