Description

cis-Isolongifolanone is a high-purity, synthetic fragrance ingredient prized for its unique woody, amber, and slightly animalic olfactory profile. It serves as a versatile and stable building block for perfumers, offering excellent blending properties and tenacity in a wide range of fragrance compositions. This compound is essential for manufacturers in the fine fragrance, personal care, and home care industries seeking to create sophisticated, long-lasting scent profiles.

Application

• Fine Fragrance Formulation: Used as a heart or base note in perfumes, eau de toilettes, and colognes to impart woody, ambery, and musky nuances.
• Personal Care Products: Incorporated into soaps, shower gels, shampoos, and deodorants for its stability and persistent scent character.
• Home Care & Air Care: A key component in detergents, fabric softeners, and air fresheners for enhancing and fixing fragrance blends.
• Functional Perfumery: Employed in technical applications where a stable, long-lasting woody note is required to mask or complement base odors.
• Flavor & Fragrance Synergy: While primarily a fragrance material, its characteristics can contribute to complex flavor creations in niche applications.
• Chemical Intermediate: Serves as a starting material or intermediate in the synthesis of other more complex fragrance molecules.

Quality Control

Our cis-Isolongifolanone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing including GC, IR, and NMR to ensure identity, purity, and olfactory consistency. Certificates of Analysis (COA) documenting key specifications such as assay, isomer purity, and organoleptic properties are provided to guarantee it meets the high standards required for fragrance applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. Keep away from heat, sparks, and open flame. This material is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light).
