Used as a green solvent in organic synthesis, particularly in pharmaceutical and fine chemical manufacturing due to its biodegradability and renewable sourcing. It serves as an alternative to traditional ethers like tetrahydrofuran (THF) and dichloromethane, offering better phase separation in aqueous reactions and improved safety profile. Commonly applied in Grignard reactions, metal-catalyzed couplings, and hydrogenations. Also used in extraction processes and as a reaction medium in polymer chemistry. Its low miscibility with water allows for easy product isolation and solvent recovery.
