Description

α-Patchoulene (CAS NO 560-32-7) is a high-purity sesquiterpene hydrocarbon, a key constituent of patchouli oil prized for its unique woody and earthy aromatic profile. This compound serves as a critical intermediate and reference standard for the fragrance, flavor, and pharmaceutical industries, where precise chemical identity and purity are paramount. It is essential for R&D laboratories, flavor and fragrance houses, and manufacturers of high-end personal care products seeking authentic and consistent patchouli characteristics.

Application

• Fragrance & Perfumery: A fundamental building block for creating and authenticating the complex, long-lasting base notes characteristic of patchouli in fine perfumes, colognes, and scented products.
• Flavoring Agent: Used as a reference standard and a component in developing sophisticated, earthy flavor profiles for gourmet foods and beverages.
• Pharmaceutical Research: Employed as a high-purity analytical standard and an intermediate in pharmacological studies investigating the bioactive properties of patchouli and related sesquiterpenes.
• Aromatherapy & Essential Oils: A key marker compound for the quality control and standardization of therapeutic-grade patchouli essential oil.
• Cosmetics & Personal Care: Incorporated into formulations for soaps, lotions, and creams to impart a distinctive, natural scent and potential skin-beneficial properties.
• Chemical Synthesis: Serves as a valuable starting material or chiral precursor for the organic synthesis of more complex fragrance molecules and fine chemicals.

Quality Control

Our α-Patchoulene is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic (GC, HPLC) and spectroscopic (IR, NMR) techniques to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized and should be handled under an inert atmosphere for long-term storage or when opening sealed containers. Keep away from heat, sparks, and open flame.
