Description
Diisopropyl ether (DIPE, CAS 108-20-3) is a symmetrical aliphatic ether also known as isopropyl ether and 2,2'-oxybispropane. It carries no E-code designation and is classified under HS code 29091990. It is commercially available under both its full name and the abbreviated form DIPE.
In food and flavour applications, DIPE functions as a solvent carrier, facilitating the extraction and delivery of flavour compounds by dissolving non-polar constituents that aqueous systems cannot accommodate. It is also used in laboratory and industrial extraction processes where its low miscibility with water enables clean phase separation, improving selectivity in liquid-liquid extraction workflows.
DIPE is supplied as a liquid in standard industrial packaging and is subject to REACH registration requirements for supply within the EU. Procurement teams should confirm grade specification against intended application, as food-contact use requires documented purity compliance. Buyers should verify current SDS and regulatory status prior to ordering.
