Запах
Докладно
Цікавий факт
Toscanol is made from estragole, the main scent molecule of tarragon and basil: the patent adds a single carbon to its side chain to close a three-membered cyclopropane ring. According to the same patent, its detection threshold, measured by olfactometer, is 80 times lower than that of estragole.
Отримання й хімія
Спосіб отримання
Fully synthetic. Toscanol is not made from eugenol or clove oil: its structure has no phenol group and no allyl chain. Patent US 7,704,942 describes its preparation from estragole by cyclopropanation of the allyl side chain (dibromomethane, zinc, copper(I) chloride), followed by distillation.

У парфумерії
Toscanol is a synthetic anisic material used to bring an anisic, agrestic and aromatic character to accords. It is offered as a substitute for basil oil, tarragon oil, synthetic estragole and safrole, at 0.1 to 5% of the concentrate, in fine fragrance and consumer products. In the patent's fougère example it blends with the anisic and spicy notes and, compared with estragole, gives more character and freshness. It is stable in most bases, including soap and candles.
