Collection: Phase Transfer Catalysts

Phase Transfer Catalysts — includes quaternary ammonium and phosphonium salts such as tetrabutylammonium, benzyldimethyltetradecylammonium, and tetrabutylphosphonium, which function to transfer ions between the organic phase and the aqueous phase in immiscible two-phase chemical reactions.

These phase transfer catalysts are used by synthetic chemists to accelerate reactions between water-soluble reagents and organic substrates, such as alkylation, nucleophilic substitution, and Williamson reactions, without requiring expensive polar aprotic solvents. These ammonium and phosphonium salts are also used in chemical industrial processes to improve reaction efficiency on a large scale.

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 T3951 2304-30-5 Tetrabutylphosphonium Chloride (ca 80% in Water), TCI C0329 67-48-1 Choline Chloride.

Pay attention to the alkyl chain length on the quaternary cation, as it affects solubility and phase transfer efficiency, as well as the physical form (solid or aqueous solution) suitable for the reaction scale. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
