Metil-2-oktinoat (list ljubičice)
Intensely green-violet with a metallic, slightly waxy quality. Methyl 2-octynoate smells like a crushed violet leaf — sharply green, vegetal, with a particular violet-like freshness.

U parfemima
Top-to-heart modifier in green, chypre, and violet-leaf compositions. Methyl 2-octynoate provides intense green-violet character at trace dosages. It is central to violet-leaf reconstructions and adds green freshness to chypre and fougère compositions. Must be used with extreme restraint — overdosing creates a harsh, metallic result. Pairs with galbanum, violet leaf absolute, and floral notes. Maximum recommended usage is very low.
