Description

3,7-Dimethylocta-1,6-Diene-3-Thiol is a high-purity sulfur-containing terpene derivative, recognized for its potent and distinctive organoleptic properties. This compound is of significant commercial interest primarily as a key flavor and fragrance intermediate, valued for its ability to impart complex, tropical, and grapefruit-like notes. It is an essential raw material for flavorists and perfumers in the food, beverage, and fine fragrance industries, where precise quality and consistent organoleptic profile are critical for product development.

Application

• Flavor & Fragrance Industry: A crucial building block for creating complex flavor profiles, particularly for tropical fruits (e.g., passionfruit, grapefruit) and enhancing citrus notes in beverages, confectionery, and dairy products.
• Perfumery: Used as a top or middle note in fine fragrances, cosmetics, and personal care products to add fresh, green, and exotic nuances.
• Food Additive Synthesis: Serves as a precursor or intermediate in the synthesis of advanced flavoring substances and aroma chemicals.
• Research & Development: Utilized in academic and industrial R&D for studying sulfur-containing natural products, aroma chemistry, and new synthetic pathways for flavor compounds.
• High-End Consumer Products: Incorporated into premium air fresheners, home care products, and candles requiring sophisticated and natural-smelling aromas.

Quality Control

Our 3,7-Dimethylocta-1,6-Diene-3-Thiol is produced and handled under strict quality management systems to ensure batch-to-batch consistency and purity required for sensitive flavor and fragrance applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards for flavor ingredients, and specifications can be tailored to meet specific customer requirements, including FCC or other food-grade guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C to maximize stability and shelf life. This compound is easily oxidized; therefore, contact with air should be minimized during handling and storage. Keep away from heat, sparks, and open flame.
