Description

α-Bulnesene is a high-purity sesquiterpene hydrocarbon, a key building block and fragrance ingredient valued for its unique woody and earthy aromatic profile. Its chemical stability and defined structure make it a critical intermediate for synthesizing more complex aroma chemicals and for high-value applications in fine chemistry. This compound is essential for manufacturers in the fragrance, flavor, and pharmaceutical industries seeking consistent, high-quality raw materials for product development and research.

Application

• Fragrance & Flavor Industry: Serves as a key intermediate and base note in the creation of sophisticated perfumes, colognes, and essential oil blends, imparting woody, amber, and earthy nuances.
• Aroma Chemical Synthesis: Used as a premium starting material or intermediate for the synthesis of other valuable sesquiterpenoids and complex fragrance molecules.
• Pharmaceutical Research: Employed as a standard or intermediate in the research and development of bioactive compounds, leveraging its specific sesquiterpene skeleton.
• Cosmetics & Personal Care: Incorporated as a fragrance component in lotions, soaps, and other cosmetic formulations where a natural, woody scent profile is desired.
• Food & Beverage Flavors: Used in trace amounts to create or enhance natural, earthy flavor profiles in specialty food products and beverages.
• Chemical Standard & Analysis: Supplied as a high-purity reference standard for GC-MS, HPLC, and other analytical methods in quality control and research laboratories.

Quality Control

Every batch of our α-Bulnesene is produced and tested under a strict quality management system to ensure it meets the high standards required for fragrance, flavor, and research applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles as verified by GC, GC-MS, and other relevant analytical techniques. Our quality commitment ensures batch-to-batch consistency and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flames.
