Application

Dicyclohexylamine was used to constitute ionic liquid matrices for bacterial analysis in matrix assisted laser desorption/ionisation mass spectrometry. It was used to develop a new palladium catalyst for Suzuki coupling reaction of aryl bromides with boronic acids. It was used as extractant in determination of gold(III) by dispersive liquid-liquid microextraction and electrothermal atomic absorption spectrometry.

A combined method with dispersive liquid-liquid microextraction (DLLME) and electrothermal atomic absorption spectrometry (ETAAS) has been developed for determining gold(III). Dicyclohexylamine, a new extractant for gold(III), showed excellent performance in DLLME. Acetone was indispensable to the quantitative extraction of gold(III)

We wished to identify metabolic signals governing changes in ornithine decarboxylase (L-ornithine carboxy-lyase, EC 4.1.1.17) activity in Neurospora crassa. By manipulations of the ornithine supply and by the use of inhibitors of the polyamine pathway, we found that spermidine negatively
