What is 3-Pentanone CAS 96-22-0?

3-Pentanone, also called diethyl ketone or DEK, is a symmetrical dialkyl ketone with CAS 96-22-0, EINECS 202-490-3 and molecular formula C₅H₁₀O. It is a colorless to pale yellow liquid with an acetone-like odor and a molecular weight of about 86.13.

What is 3-Pentanone used for?

It is mainly used as a medium-evaporating ketone solvent in coatings, lacquers, inks, adhesives and resin systems. It also serves as an intermediate in pharmaceutical synthesis and vitamin E precursor chemistry, and as a building block in organic reactions.

Are 3-Pentanone, Diethyl Ketone, DEK and Propione the same product?

Yes. 3-Pentanone, diethyl ketone, DEK, propione and pentan-3-one are common names for the same symmetrical ketone with CAS 96-22-0. It is different from 2-pentanone, the asymmetric isomer commonly known as methyl propyl ketone.

What specifications should be checked for industrial-grade 3-Pentanone?

Confirm assay, water, acidity, color and related ketone impurities. Boiling range and density are also useful identity and quality checks, because residual water or impurities can affect solvent performance and downstream synthesis.
