Verbenone

Verbenone is an organic compound classified as a monoterpene ketone. It is related to other terpenoids and can be derived from verbenol by oxidation. It is found in trace amounts in the essential oils of several plants and has a characteristic woody, pine-like odor.

In nature, verbenone occurs in small amounts in certain species of Verbenaceae and other plants; it can also be formed synthetically from verbenol or by oxidation of related compounds.

In forestry, verbenone is used as an anti-aggregation pheromone for bark beetles. When released, it signals stressed or over-populated trees and discourages beetles from initiating new galleries, helping to protect standing trees. It is deployed in dispensers or combined with attractants for monitoring and management of beetle populations.

In perfumery and flavor chemistry, verbenone is used as a fragrance ingredient or odor note, providing a resinous, woody nuance. It is not as common as some other monoterpenes due to cost and availability, but it appears in some formulations and essential oil blends.

Safety and regulation: Verbenone is not considered highly hazardous under normal handling conditions. Standard chemical hygiene applies, and regulatory status varies by country.
