Description

(-)-α-Cedrene CAS NO 469-61-4 is a high-purity, naturally derived sesquiterpene known for its characteristic woody, amber-like aroma. This enantiomerically pure compound is valued for its consistent olfactory profile and chemical stability, making it a critical building block in fine fragrance creation. It is primarily sought after by manufacturers in the flavors and fragrances, cosmetics, and aromatherapy industries for premium product formulations.

Application

• Fine Fragrance Compound: A key ingredient in high-end perfumery for creating woody, ambery, and balsamic base notes.
• Flavor Enhancer: Used in trace amounts to impart subtle woody nuances in specialty food and beverage flavorings.
• Cosmetic Ingredient: Incorporated into personal care products like soaps, lotions, and creams for its fragrance and potential fixative properties.
• Aromatherapy & Wellness: Employed in essential oil blends and diffuser products for its grounding and calming aromatic qualities.
• Chemical Intermediate: Serves as a chiral starting material or reference standard in organic synthesis and analytical chemistry.
• Household & Industrial Fragrances: Used in air fresheners, detergents, and other scented products requiring a stable, long-lasting woody note.
