title: Preparation and properties of tetramethyl-dipicrylamine.
abstract: Tetramethyldipicrylamine has been synthesised. It gives precipitates with ammonium, potassium, rubidium and caesium ions, that vary widely in crystalline form and offer a possibility of qualitative usage in chemical microscopy. The potassium salt is of sufficiently low solubility to be of analytical interest.
