Trans-3-Nonen-2-on

Nonene is a colorless or pale yellow liquid with a delicate a floral note.

Gives freshness to floral fragrance compositions and is recommended as a replacement for methyl 2-octoate.

The synthesis consists heptanal condensation with malonic acid, decarboxylation and later methanol esterification. Widely used as a substrate in organic synthesis, especially in enantioselective addition reactions coupled with organozinc reagents catalysed with copper compounds.

Trans-3-Nonen-2-on is also used:

- as a substrate for studying the kinetics of the steady state oxidation of NADPH

- in the preparation of azine-quinolone

- CBD production substrate,
