Diisopropyl ether

Diisopropyl ether (CAS 108-20-3), also known as isopropyl ether or DIPE, is a low-polarity ether solvent used across pharmaceutical, chemical, and flavor extraction processes. Its selective solvency and low water miscibility make it a practical choice for liquid-liquid extraction and azeotropic drying operations in various industrial settings.

In pharmaceutical and fine chemical manufacturing, DIPE is used as an extraction solvent to isolate active compounds and intermediates from aqueous reaction mixtures effectively. Flavor and fragrance producers use it to extract and concentrate aromatic compounds from natural raw materials, where clean solvent removal is critical to end-product quality.

It also functions as a reaction solvent in organic synthesis, particularly where a low-boiling, recoverable ether is preferred over higher-residue alternatives for the process. In fuel blending, DIPE serves as an oxygenate additive to improve octane ratings in gasoline formulations, demonstrating its versatility across different chemical sectors.

Diisopropyl ether is supplied as a liquid in drum and IBC quantities, with bulk tanker options available for large-volume industrial buyers requiring consistent supply chains. Technical grade is the standard commercial offering, with anhydrous and stabilized variants available to meet specific handling and storage requirements for purity above 99%.
