General description
Tetramethylammonium chloride is a quaternary ammonium salt commonly used as a catalyst due to its thermal stability and also tolerance towards strong aqueous bases or nucleophiles.
Application
Tetramethylammonium chloride along with N-hydroxyphthalimide and xanthone may be used as an efficient chloride catalytic system for the aerobic oxidation of hydrocarbons to form the corresponding oxygenated compounds. It may also be used as a phase transfer catalyst for the synthesis of aryl fluorides via selective chloride/fluoride exchange reaction of activated aryl chlorides with potassium fluoride in solid-liquid phase.

Biological functions depend on biomolecular assembly processes. Assemblies of lipid bilayers, actins, microtubules, or chromosomes are indispensable for cellular functions. These hierarchical assembly processes are reasonably predictable by understanding chemical structures of the defined building blocks and their interactions. However
