Tetraethylammonium Hydroxide (10% in Water) from TCI (product code T0096) is an aqueous solution of a quaternary ammonium base, in which the tetraethylammonium cation is paired with the hydroxide ion. In the laboratory it serves as a strong organic base that contains no alkali metal ions. It can replace sodium or potassium hydroxide wherever metal ions are unwanted. Because the solution comes at a fixed concentration, it is easy to measure and use straight from the bottle, so there is no need to prepare a solution from a solid.

Chemists choose this reagent because it combines strong basicity with a large, soluble organic cation. The absence of sodium or potassium ions matters most in the synthesis of zeolites and other porous materials. In that work, the tetraethylammonium cation also acts as a structure-directing agent that shapes the pore architecture of the crystal. Calcination removes the organic cation without leaving any metal residue, so the final framework stays clean. The cation's solubility and stable behaviour in solution also make the reagent useful well beyond materials chemistry.

In Indonesia, this solution is in steady demand at university research laboratories, catalysis and materials science groups, and industrial R&D facilities. Researchers working on zeolite catalysts and porous adsorbents use it as a metal-free base and template. Organic synthesis laboratories use it as a base catalyst or phase-transfer base. Analytical laboratories use it to adjust pH and as an ion-pairing reagent. The ready-to-use aqueous form suits routine work and research-scale experiments alike.

Zeolite and molecular sieve synthesis: the tetraethylammonium cation acts as a structure-directing agent that shapes the crystal pores, and it supplies hydroxide without adding sodium or potassium.
Porous material preparation: because the organic cation burns off during calcination without leaving metal residue, the reagent suits the preparation of clean, metal-free porous frameworks for catalysis and adsorption research.
Base catalysis in organic synthesis: as a strong quaternary ammonium base, it can catalyse base-promoted reactions where an organic, metal-free base gives better compatibility than inorganic hydroxides.
Phase-transfer reactions: the large, soluble tetraethylammonium cation lets the solution act as a phase-transfer base, carrying hydroxide reactivity between aqueous and organic phases during synthesis.
Analytical pH adjustment and ion pairing: analysts use it to adjust pH without adding alkali metal ions and as an ion-pairing reagent that improves the separation and analysis of charged species.

Tetraethylammonium hydroxide solution is a strong base and should be handled as a corrosive material. Keep the container tightly closed so the solution does not absorb carbon dioxide from the air, since that gradually lowers its basicity. Store it in a cool, dry, well-ventilated place away from acids and incompatible materials. Use the original container or another chemically resistant container made of a material suited to alkaline solutions. When handling, wear chemical-resistant gloves, safety goggles and a lab coat, and work in a fume hood or well-ventilated area. Avoid contact with skin and eyes. If contact occurs, rinse thoroughly with water. Always read the manufacturer's Safety Data Sheet before use and dispose of waste according to local regulations.
