Description
- 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.
