Utilisation

Uses

Uses in perfumery :

Trans-2-Hexenol is used in green notes and unripe fruit accords. Also used in stem notes for floral accords. Makes a honeysuckle more vegetal and fresh. Allows you to nuance floral notes. Gives a fresh appearance to jasmine, freesia or peony.

Year of discovery :

Data not available.

Natural availability :

Trans-2-Hexenol is found naturally in Roman Chamomile EO and Violet Leaf Absolute, and can therefore be naturally extracted, although synthetic trans-2-Hexenol is more often used.

Isomerism :

Trans-2-Hexenol has a more fruity, apple-like smell than cis-3-Hexenol, which is purely green. This is why it is more often used in fruity accords than cis-3-Hexenol, that is used in flowery accords. Cis-2-Hexenol has a very green smell and also more fruity than cis-3-Hexenol.

Synthesis precursor :

Trans-2-Hexenol is a precursor to the synthesis of trans-2-Hexenyl acetate and other esters made from this alcohol.

Synthesis route :

Trans-2-Hexenol is synthesized by the same route as cis-3-Hexenol, or by an isomerization in an acid medium of cis-3-Hexenol.
