Description

S-3,7-Dimethyl-1-Octanol is a chiral, branched-chain fatty alcohol with a distinctive, pleasant odor. This compound serves as a valuable chiral intermediate and fragrance ingredient, prized for its stereochemical purity and organoleptic properties. It is primarily utilized by manufacturers in the flavor & fragrance, pharmaceutical, and fine chemical synthesis industries seeking high-purity, enantiomerically defined building blocks.

Application

• Fragrance & Flavor Ingredient: Used as a chiral component in the synthesis of high-value aroma chemicals and perfumery compounds for its specific olfactory characteristics.
• Pharmaceutical Intermediate: Acts as a key chiral synthon in the production of active pharmaceutical ingredients (APIs) where stereochemistry is critical for biological activity.
• Liquid Crystal Materials: Employed in the research and development of chiral dopants for liquid crystal displays (LCDs) and advanced optical materials.
• Asymmetric Synthesis: Serves as a chiral auxiliary or starting material in catalytic asymmetric reactions to induce enantioselectivity.
• Specialty Surfactants: Utilized in the synthesis of enantiomerically pure or enriched surfactants for specialized applications.
• Chemical Research: A reference standard and building block in organic chemistry research and development laboratories.

Quality Control

Our S-3,7-Dimethyl-1-Octanol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by GC or HPLC, identity confirmation (IR, NMR), and determination of chemical purity and specific optical rotation. Certificates of Analysis (COA) detailing all specifications are provided to ensure compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its properties of being highly volatile and easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in opened containers.
