Di-n-butyl ether is an organic solvent and ether compound primarily used as a solvent in industrial applications, including Grignard and other organometallic reactions, extractions, and the dissolution of resins and oils; its high cetane number has also led to its study as a diesel fuel additive. It is also employed in the synthesis of other chemicals and as a laboratory reagent. This clear, flammable liquid has a CAS number of 142-96-1, with the molecular formula C8H18O and a molecular weight of 130.23 g/mol. It is typically stored at ambient conditions and carries a signal word of "Warning" for safety classification. Molekula supplies Di-n-butyl ether from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
