Used as a co-solvent in lithium-ion battery electrolytes due to its low viscosity, wide liquid range, and ability to enhance low-temperature performance and ionic conductivity when blended with high-dielectric constant carbonate solvents. It effectively dissolves lithium salts in combination with other components. Also serves as a methylating and ethylating agent in organic synthesis, particularly in pharmaceutical and agrochemical manufacturing. Acts as an intermediate in the production of polycarbonates and other specialty chemicals. Its low toxicity and biodegradability make it suitable for environmentally friendly chemical processes. Additionally, it is used as an oxygenate additive in fuel formulations to improve combustion quality and reduce emissions from certain engines.
