Collection: Ammonium Salts [Phase Transfer Catalysts]

Ammonium Salts [Phase Transfer Catalysts] — includes quaternary ammonium salts with variations in alkyl chain and functional groups, ranging from short-alkyl compounds to long-chain surfactants, which function to transport ions between immiscible phases. The ionic nature and hydrophilic-lipophilic balance of their structures make them key components in phase-transfer catalysis systems.

Ammonium Salts are used in organic synthesis to accelerate reactions between reagents in the aqueous and organic phases, for example alkylation, nucleophilic substitution, and etherification reactions without polar aprotic solvents. Process chemists and academic research laboratories use them to simplify two-phase reaction workflows and improve ion mixing efficiency at small and medium scales.

Example products in this collection: TCI A0208 139-08-2 Benzyldimethyltetradecylammonium Chloride, TCI B5798 2650-51-3 Butyltrimethylammonium Bromide, TCI T4175 1516-27-4 N,N,N-Trimethylprop-2-en-1-aminium Chloride, TCI B6051 3779-42-8 (3-Bromopropyl)trimethylammonium Bromide, TCI T4131 1941-24-8 Tetramethylammonium Nitrate, TCI C0172 999-81-5 Chlorocholine Chloride, TCI T3923 N,N,N-Tris(polyoxyethylene)-N-methylammonium Hydroxide (55-65% in Water) (stabilized with MEHQ), TCI C0329 67-48-1 Choline Chloride.

Choose based on alkyl chain length, counter anion (chloride, bromide, nitrate), and physical form—crystalline solid or aqueous solution—which determines solubility and ease of handling. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
