General description
Trimethylphenylammonium hydroxide solution (TMPAH) is a quaternary ammonium compound that is commonly used as a strong base in organic synthesis. It is also used as a deprotecting agent for the removal of t-butoxycarbonyl (Boc) groups from amino acids or peptides and benzyl protecting groups from alcohols or amines.
Application
Trimethylphenylammonium hydroxide solution can be used to initiate the polymerization of the monomer 1,8-dihydroxymethyl-1,3,5,7-octatetrayne (DHOT) for the preparation of polymer nanospheres. It is also used as a base in the synthesis of alkyl 3-nitroacrylates via aldol reaction with nitroacetaldehyde or nitroacetone.
