A powerful green-fruity nitrile with a natural galbanum-like character. Opens with a sharp, sappy green facet reminiscent of crushed leaves and unripe fruit, developing into a tropical fruity nuance (pear, apple skin) with a subtle waxy undertone. Often used as a more stable alternative to cis-3-hexenyl esters for green-fruity effects.AI · claude-opus-4-7
