Description

[R,(+)]-3,7-Dimethyl-7-Octenal is a high-purity, chiral aldehyde valued for its unique olfactory profile and role as a key chiral intermediate in fine chemical synthesis. Its distinct enantiomeric purity makes it a critical component for creating sophisticated fragrance accords and for applications requiring specific stereochemistry. This compound is primarily sought by manufacturers in the fragrance and flavor industry, as well as by research and development laboratories in pharmaceutical and agrochemical sectors.

Application

• Fragrance Ingredient: Used as a key component in premium perfumery for its fresh, citrusy, and aldehyde character, often found in fine fragrances, personal care products, and household cleaners.
• Flavor Modifier: Employed in flavor compositions to impart or enhance citrus and green notes in food and beverage products.
• Chiral Building Block: Serves as a valuable intermediate in the asymmetric synthesis of more complex molecules for pharmaceutical and agrochemical research.
• Chemical Synthesis: Utilized in organic synthesis for the preparation of other terpenoid derivatives and fine chemicals.
• Aroma Chemical Production: Acts as a precursor in the manufacturing of other aroma chemicals and fragrance compounds.
