Description

[S,(-)]-2,6-Dimethyl-1,5-Heptadien-3-Ol CAS NO 80232-55-9 is a high-purity, optically active terpene alcohol, specifically the (S)-enantiomer of linalool oxide. This compound is valued for its distinct, refined olfactory profile, making it a critical chiral building block and fragrance ingredient. It is primarily sought after by manufacturers in the flavor and fragrance industry, as well as by research and development laboratories working on stereoselective synthesis and chiral auxiliaries.

Application

• Fragrance & Flavor Industry: As a key chiral intermediate for synthesizing high-value aroma chemicals with specific stereochemistry, contributing to complex, naturalistic scent profiles in perfumes, cosmetics, and fine fragrances.
• Pharmaceutical Intermediates: Utilized in the research and development of active pharmaceutical ingredients (APIs) where the specific (S)-configuration is required for biological activity or metabolic pathway studies.
• Agrochemical Synthesis: Serves as a chiral synthon in the production of certain pesticides and herbicides, where enantiomeric purity can influence efficacy and environmental impact.
• Academic & Industrial Research: Employed as a standard or reagent in asymmetric catalysis studies, organic synthesis methodologies, and for investigating structure-odor relationships.
• Specialty Chemicals: Used in the formulation of advanced materials, liquid crystals, or as a ligand in metal-catalyzed reactions requiring specific chirality.

Quality Control

Our [S,(-)]-2,6-Dimethyl-1,5-Heptadien-3-Ol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by GC or HPLC, to ensure high enantiomeric excess (e.e.) and chemical purity. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to guarantee consistency and traceability for your critical applications.

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 product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain its chiral integrity and olfactory quality. Keep away from heat, sparks, and open flames.
