Description

Tetrahydronootkatone is a saturated derivative of the sesquiterpenoid nootkatone, prized for its enhanced stability and refined organoleptic profile. This compound is a high-value ingredient for creating sophisticated, long-lasting woody and ambergris-like fragrance accords. It is essential for manufacturers in the flavor and fragrance industry seeking to develop premium perfumes, fine fragrances, and specialty aroma chemicals. The material is supplied under rigorous quality control to ensure batch-to-batch consistency for demanding commercial applications.

Application

• Fragrance Formulation: A key building block in high-end perfumery for creating deep, woody, and ambery base notes in fine fragrances, eau de parfums, and colognes.
• Flavor Enhancement: Used in trace amounts to impart complex, nuanced woody and citrus-tinged nuances in specialty food and beverage flavorings.
• Aroma Chemical Synthesis: Serves as a valuable intermediate or starting material for the synthesis of other novel fragrance molecules and sesquiterpenoid derivatives.
• Personal Care Products: Incorporated into luxury soaps, lotions, and hair care products to provide a premium, persistent scent character.
• Household & Air Care: Used in premium air fresheners, diffusers, and cleaning products to deliver a sophisticated and stable fragrance profile.

Quality Control

Our Tetrahydronootkatone is produced and tested to meet the exacting standards of the flavor and fragrance industry. Each batch is analyzed using advanced chromatographic and spectroscopic techniques to ensure identity, purity, and olfactory profile consistency. A comprehensive Certificate of Analysis (COA) detailing purity, specific rotation, and impurity limits is provided with every shipment, ensuring full traceability and compliance with relevant quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) after opening to maintain stability and prevent degradation. Keep away from heat, sparks, and open flame.
