Description

(+)-β-Cedrene CAS NO 546-28-1 is a high-purity, naturally-derived sesquiterpene known for its characteristic woody, amber-like aroma. This compound is valued for its role as a key fragrance intermediate and chiral building block in fine chemical synthesis. It is essential for manufacturers in the flavor and fragrance industry, as well as for research institutions focused on terpene chemistry and natural product development.

Application

• Fragrance Formulation: Serves as a core ingredient and fixative in premium perfumes, colognes, and personal care products to impart warm, woody, and ambery notes.
• Flavor Enhancement: Used in the creation of complex flavor profiles for food and beverages, contributing subtle woody and spicy nuances.
• Aromatherapy & Essential Oils: A valuable component in therapeutic blends and natural essential oil reconstructions for its grounding aromatic properties.
• Fine Chemical Synthesis: Acts as a chiral starting material or intermediate in the synthesis of more complex fragrance molecules and pharmaceuticals.
• Research & Development: Utilized in academic and industrial R&D for studying terpene biosynthesis, olfactory receptors, and natural product chemistry.
• Household & Industrial Products: Incorporated into air fresheners, detergents, and cleaning products to provide a long-lasting, pleasant scent.

Quality Control

Our (+)-β-Cedrene is produced and tested under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including GC, GC-MS, and chiral HPLC to verify identity, potency, and enantiomeric excess. A comprehensive Certificate of Analysis (COA) detailing purity, physical constants, and chromatographic data is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. Due to its highly volatile nature, keep away from heat, sparks, and open flame. For long-term storage, consider sealing under an inert atmosphere such as nitrogen to prevent oxidation.
