Year of discovery :

Synthesis route :

Cis-3-Hexenyl Formiate results from an esterification of cis-3-Hexenol with formic acid (or methanoic acid), in the presence of an acid catalysor as concentrated sulfuric acid. Using formic anhydride or chloromethanoic acid can also enhance the yield of this reaction.

Synthesis precursor :

Cis-3-Hexenyl Formate is not a precursor to the synthesis of another compound of olfactory interest.

Isomerism :

Trans-3-Hexenyl Formate, the cis-3-Hexenyl Formate diastereoisomer, is almost not used in perfumes. One positional isomer called trans-2-Hexenyl Formate is sometimes used for its rummy green apple note.

Natural availability :

Cis-3-Hexenyl Formate can be extracted from Corn Mint EO, and is found in raspberry and mango in trace amounts.

Allergens :

This ingredient does not contain any allergen.

Uses in perfumery :

Cis-3-Hexenyl Formate is used in small quantities in some perfumes to give a juicy aspect to an apple or pear note. It can be used in combination with other cis-3-Hexenol derivatives to give many effects and bring roundness to fruity notes. It can be used with Galbanum EO and Violet Leaf Absolute notes.

Other names :

cis-3-Hexenyl formiate, cis-3-hexen-1-yl formiate, cis-3-hexen-1-yl formate, cis-3-hexen-1-yl formiate, cis-hex-3-enyl formate, cis-hex-3-enyl formiate, cis-hex-3-en-1-yl formate, cis-hex-3-en-1-yl formiate, (Z)-3-hexen-1-yl formate, (Z)-3-hexen-1-yl formiate

Other comments :

Cis-3-Hexenyl Formate has a very etheric smell making the difference with cis-3-Hexenyl Acetate, less heady.
