Uses
Uses in perfumery :
Brings naturalness to fruity notes. Thanks to its green (cut grass) and its yellow fruit facets, cis-3-hexenyl isobutyrate gives a ripe note to fruits. Interesting for the plum notes.
Suppliers recommend to use it below 1%.
Year of discovery :
Data not available.
Natural availability :
Reported found in guava, spearmint EO. Do not exist in its natural state but there is a nature identical quality for cis-3-Hexenyl IsoButyrate
Isomerism :
Cis-3-Hexenyl Isobutyrate is the positional isomer of cis-3-Hexenyl Butyrate and trans-2-Hexenyl Isobutyrate. The latter are less commonly used in perfumery, but have a similar odor. Trans-2-Hexenyl Isobutyrate has a more fruity and less green, apple-like smell. Trans-3-Hexenyl Isobutyrate, is not used in perfumery.
Synthesis precursor :
cis-3-Hexenyl IsoButyrate is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Cis-3-Hexenyl Isobutyrate is synthesized by an esterification process between Isobutyric acid (or 2-methylpropanoic acid) and cis-3-Hexenol. This reaction involves acid catalysis using a small amount of a strong acid such as concentrated sulphuric acid.
