Description

Isolongifolene is a high-purity, highly volatile sesquiterpene hydrocarbon valued for its unique woody, ambergris-like odor profile and excellent stability. This compound serves as a versatile and cost-effective building block in the synthesis of more complex fragrance ingredients, particularly for woody and amber accords. It is essential for manufacturers in the flavors and fragrances (F&F) industry, as well as for research and development in fine chemical synthesis.

Application

• Fragrance Ingredient: A key intermediate and starting material for the synthesis of high-value aroma chemicals like norlabdane oxide and other amber/woody notes.
• Flavor & Fragrance (F&F) Formulations: Used as a component in creating complex perfume bases, soaps, detergents, and cosmetic products for its tenacious woody character.
• Chemical Synthesis: Acts as a chiral starting material or intermediate in organic synthesis for pharmaceuticals and other fine chemicals due to its complex, rigid tricyclic structure.
• Industrial Aromatics: Employed in air care products, household cleaners, and industrial deodorizers to provide long-lasting background notes.
• Research & Development: Utilized in academic and industrial labs for studying terpene chemistry, reaction pathways, and the development of novel synthetic methodologies.

Quality Control

Our Isolongifolene is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as identity, assay, and impurity profiles. Our quality commitment aligns with industry best practices for fragrance ingredients, ensuring reliable performance in your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain quality. Recommended storage temperature is 2-25°C.
