(1S)-(-)-Verbenone is a naturally occurring terpenoid ketone derived from pinene oxidation, widely used as a pheromone disruptor in pest control—particularly effective against bark beetles—and as a fragrance compound in perfumery and flavorings. It appears as a white to pale yellow crystalline solid with a fresh, woody aroma. CAS 80-57-9, molecular formula C10H16O, purity ≥95% (HPLC), specific rotation [-135° to -145°], melting point 68–72°C, and solubility in ethanol and acetone. Non-hazardous under normal conditions. Molekula supplies (1S)-(-)-Verbenone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
