What is Caryophyllene Oxide CAS 1139-30-6?

Caryophyllene oxide, also called beta-caryophyllene epoxide, is an oxygenated sesquiterpene with molecular formula C15H24O and molecular weight about 220.35. It is supplied as a white crystalline solid or pale yellow/colorless viscous material with a woody, spicy odor.

How is caryophyllene oxide different from beta-caryophyllene?

Beta-caryophyllene is the unsaturated sesquiterpene precursor, while caryophyllene oxide contains an epoxide ring in place of that alkene functionality. This change raises the melting point, alters polarity and reactivity, and gives the material a different odor profile.

Why is it used as a fragrance fixative?

Its relatively high boiling point and low volatility help slow the evaporation of more volatile fragrance components, adding longevity and depth. The woody-spicy character makes it useful in industrial fragrances, household products, soaps, and detergents.

Can it be used as a chemical intermediate?

Yes. The epoxide ring and sesquiterpene backbone make caryophyllene oxide a useful starting material for preparing terpenoid derivatives and specialized industrial compounds. The specific reactivity depends on the reaction conditions and desired downstream chemistry.

What solubility and storage conditions should be considered?

It is soluble in alcohol and fixed oils but practically insoluble in water. Store it tightly closed in a cool, dry place away from strong light and heat to protect the epoxide structure and prevent degradation.

Caryophyllene Oxide CAS 1139-30-6

Caryophyllene Oxide CAS 1139-30-6 is a bicyclic sesquiterpene epoxy derivative serving as a critical aromatic fixative and chemical intermediate within industrial terpenoid chemistry. As an oxygenated derivative of caryophyllene, the molecule functions through its stable epoxide ring to provide wood-like olfactory stability and structural integrity in complex chemical matrices. This crystalline or viscous material is primarily utilized as a precursor in fine chemical synthesis or as a stabilizing agent in industrial-scale fragrance compounding where resistance to oxidative degradation is required for bulk processing. We ensure consistent procurement through competitive factory pricing and the capability to deliver customized specifications for diverse industrial purity requirements. Each shipment is fully supported by MSDS, TDS, COA verification to ensure technical compliance and reliability for continuous bulk supply in the global chemical market.
