Description

(Z)-7-Decen-5-Olide is a high-purity, unsaturated lactone valued for its unique organoleptic properties. This compound serves as a key intermediate and fragrance ingredient, prized for its ability to impart creamy, fatty, and peach-like nuances to complex scent profiles. It is essential for manufacturers in the flavor and fragrance, fine chemical synthesis, and cosmetic industries seeking to develop sophisticated and natural-smelling products.

Application

• Fragrance Formulation: A key component in creating and enhancing perfumes, colognes, and personal care products with creamy, fatty, and fruity (peach, apricot) olfactory notes.
• Flavor Enhancement: Used as a flavoring agent or modifier in food and beverage applications to impart creamy, buttery, or ripe fruit characteristics.
• Cosmetic Ingredients: Incorporated into high-end skincare and cosmetic formulations for its functional properties and subtle, pleasant scent.
• Fine Chemical Synthesis: Serves as a valuable chiral building block and intermediate in the synthesis of more complex organic molecules for pharmaceutical and agrochemical research.
• Functional Fluids & Additives: Potential use in specialty lubricants or polymer additives where specific lactone functionality is required.
