Methyl Tert-Butyl Ether (CAS 1634-04-4) is a volatile, clear, colorless organic ether primarily utilized as a high-octane oxygenate agent in the formulation of cleaner-burning gasoline fuels and as a specialized solvent in pharmaceutical extraction processes. This aliphatic ether functions as a critical blending component to enhance combustion efficiency and reduce tailpipe emissions, while also serving as a stable reaction medium for Grignard syntheses and chromatographic applications due to its resistance to peroxide formation. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside comprehensive technical documentation, including MSDS, TDS, COA.

use
It is mainly used as a gasoline additive, with excellent explosion resistance, increasing octane number, and can also be cracked to produce isobutene. It has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved to be used as an analytical solvent, extractant, in chromatography, especially in high-pressure liquid chromatography, as a deagent, and with some polar solvents such as water, methanol, ethanol, etc. to form azeotropes. Methyl tert-butyl ether also has a mild anesthetic effect.
Storage method:
Store in a cool, ventilated warehouse. Stay away from fire and heat sources. The temperature should not exceed 37°C. Keep the container tightly sealed. It should be stored separately from the oxidizing agent and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leak emergency treatment equipment and appropriate containment materials.
FAQ - Technical & Supply Chain
