Description

(E)-α-Bergamotene,(-)-trans-α-Bergamotene is a high-purity sesquiterpene hydrocarbon, a key component of natural bergamot and other essential oils. This compound is valued for its role as a high-quality fragrance intermediate and flavoring agent, providing authentic woody, spicy, and balsamic olfactory notes. It is essential for manufacturers in the flavor & fragrance (F&F), cosmetics, and aromatherapy industries seeking consistent, natural-character ingredients for premium formulations.

Application

• Fragrance Compound Formulation: Serves as a core building block for creating complex perfume accords with woody, spicy, and balsamic characteristics.
• Flavor Enhancement: Used in the synthesis of flavoring substances to impart natural, earthy nuances to food and beverage products.
• Cosmetic & Personal Care: Incorporated as a fragrance ingredient in soaps, lotions, creams, and other scented personal care items.
• Aromatherapy & Wellness: A key constituent in essential oil blends and diffuser products for its potential calming and grounding aromatic properties.
• Chemical Synthesis: Acts as a chiral starting material or intermediate in the organic synthesis of more complex sesquiterpenoids and fine chemicals.
• Academic & Industrial Research: Used as a reference standard in analytical chemistry (GC, GC-MS) and for studying terpene biosynthesis and biological activity.
