Estragole a.k.a Methyl Chavicol Aroma Chemical
CAS# 140-67-0

Estragole (also known as Methyl Chavicol, CAS# 140-67-0) is an aromatic molecule naturally present in basil, tarragon, fennel and star anise. It carries a distinctive spicy–herbal character, reminiscent of anise and licorice, with a warm sweetness and a fresh green nuance of basil leaf. The overall impression is sweet, warm, slightly sharp in the top notes but softening over time, evoking both culinary accords and a refined modern East–meets–West style.

In perfumery, Estragole is used to build and reinforce anise, licorice and culinary herb facets, as well as fougère–aromatic structures and scents inspired by the kitchen, bar, or patisserie. Even in very small amounts, it can bring liveliness to floral–herbal compositions, deepen anisic tones, and enhance the natural realism of basil, tarragon, and liqueur-like notes such as absinthe or pastis. Its profile is vivid and well-defined without feeling crude, adding personality and dynamism to the formula.

From a technical perspective, Estragole is a colorless to pale yellow liquid with medium to relatively high volatility, good diffusion, and easy solubility in ethanol, most professional fragrance solvents and perfume oils. It is a high-impact material typically used at low dosage levels, and should be handled in accordance with applicable safety guidelines and industry standards. Store in a cool, dry place, away from direct light, and keep containers tightly closed after use to limit oxidation and maintain olfactory quality.
