Description

Ar-Curcumene is a naturally occurring aromatic sesquiterpene, a key constituent of turmeric and other essential oils, known for its distinct woody and spicy aroma. This high-purity compound is valued for its role as a versatile intermediate and a reference standard in analytical chemistry. It is essential for manufacturers and R&D laboratories in the fragrance, flavor, and pharmaceutical industries seeking consistent, high-quality raw materials for product development and quality control.

Application

• Fragrance & Flavor Industry: A key aromatic ingredient and building block for creating complex, warm, woody, and spicy accords in perfumes, cosmetics, and food flavorings.
• Pharmaceutical Research: Serves as a critical reference standard and analytical marker for the identification and quantification of turmeric-derived compounds in herbal extracts and finished products.
• Natural Product Synthesis: Used as a chiral starting material or intermediate in the organic synthesis of more complex sesquiterpenoids and bioactive molecules.
• Essential Oil Standardization: Employed in the quality control of turmeric oil, ginger oil, and other essential oils to authenticate and standardize their chemical profile.
• Aroma Chemicals: A fundamental component in the production of sophisticated aroma chemicals for high-end personal and home care products.

Quality Control

Our Ar-Curcumene is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, HPLC, GC-MS, NMR) to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support compliance with relevant standards for research and industrial use.

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 light-sensitive and easily oxidized; for long-term storage, consider filling the headspace with an inert gas (e.g., nitrogen or argon) to maintain stability.
