Potassium t-Butoxide is a high-performance strong organic base widely used in advanced organic synthesis. With the chemical formula C₄H₉KO and a molecular weight of 112.21 g/mol, it is supplied as a white to off-white solid powder with excellent reactivity and consistent quality.
This product features a density of 0.929 g/cm³, a melting point of 240 °C, and a boiling point of 275 °C. It is highly soluble in tetrahydrofuran (THF) and reacts readily with water, making it particularly suitable for anhydrous reaction systems.
Due to its strong basicity and relatively low nucleophilicity, potassium t-butoxide is an ideal reagent for dehydrohalogenation of halogenated hydrocarbons, as well as condensation, rearrangement, and ring-opening reactions. It is also recognized as one of the most effective bases in alcoholate–haloform reactions for generating dihalocarbenes, delivering high efficiency and excellent selectivity.
Our potassium t-butoxide is produced via the controlled reaction of tert-butanol with metallic potassium, ensuring high purity, stable performance, and batch-to-batch consistency. It is widely used in the chemical, pharmaceutical, and agrochemical industries, trusted by manufacturers and research laboratories worldwide.
As a corrosive and highly hygroscopic organic base, the product is packed in airtight containers and should be stored in a cool, dry, and well-ventilated place, away from moisture, heat, direct sunlight, and ignition sources.

Our company currently possesses a globally exclusive and unique technology, with ample raw material supply and procurement costs far lower than those of potassium metal processes. Compared to the direct reaction of potassium metal with tert-butanol, this method avoids the risks of potassium metal flammability and explosion upon contact with water/air, making the production process easier to control and reducing safety hazards.
It also boasts superior environmental friendliness, with water as the only reaction byproduct and no toxic or harmful pollutants generated, aligning with green chemistry trends and minimizing the burden of subsequent wastewater treatment.
