Diethyl ketone

Diethyl ketone (CAS 96-22-0), also known as DEK or propione, is a mid-chain ketone solvent used across pharmaceutical, cosmetic, and flavor applications. It combines effective solvency with a characteristic ethereal, fruity odor. This chemical is useful in both formulation and flavoring contexts. In pharmaceutical manufacturing, DEK functions as a process solvent for active ingredient synthesis and recrystallization steps where controlled evaporation is required.

Flavor houses incorporate it as a flavoring agent in food products. Its clean, acetone-like yet fruity character contributes to artificial fruit, dairy, and confectionery profiles in various food-grade applications. In personal care and cosmetic formulations, it acts as a carrier solvent for resins, waxes, and film-forming polymers. It is frequently utilized in nail care and specialty coating products for industrial use.

Specialty coatings and ink manufacturers also source DEK as an alternative to MEK. It is preferred where faster evaporation or different solvency parameters are needed for specific manufacturing processes. Diethyl ketone is supplied as a clear liquid in drums and IBC totes, with bulk quantities available for industrial users. Standard commercial grades include technical and high-purity variants for the market.

These variants are suitable for pharmaceutical process use and meet rigorous industry requirements. Food-grade supply aligned with flavor industry specifications is available from select producers for flavoring applications.
