Description

Ethyl trans-4-Decenoate is a high-purity, unsaturated fatty acid ester characterized by its specific trans-configuration at the 4-position. This compound serves as a valuable synthetic intermediate and flavor/fragrance ingredient, prized for its unique organoleptic properties and chemical reactivity. It is primarily utilized by manufacturers in the flavor & fragrance, pharmaceutical, and fine chemical synthesis industries seeking to develop sophisticated organoleptic profiles or complex molecular structures.

Application

• Flavor & Fragrance (F&F) Industry: Used as a key building block or modifier in the synthesis of complex fruity, waxy, or creamy flavor notes and fragrance compounds.
• Pharmaceutical Intermediates: Serves as a crucial chiral synthon or precursor in the multi-step synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Fine Chemical Synthesis: Acts as a versatile intermediate for organic synthesis, including cross-coupling reactions, hydrogenation, or functional group transformations in research and development.
• Food Additive Precursor: Employed in the production of esters and other derivatives that may function as food-grade flavoring agents or texturizers.
• Cosmetic Ingredients: Utilized in the formulation of high-end perfumes, lotions, and personal care products for its specific scent profile and stability.
• Research & Development: Provides a standard or starting material for academic and industrial research in organic chemistry, catalysis, and sensory science.

Quality Control

Our Ethyl trans-4-Decenoate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity, isomeric purity, and identity. Certificates of Analysis (COA) detailing purity, specific rotation (if applicable), and impurity profiles are available upon request to support your quality assurance protocols.

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). Keep away from strong oxidizing agents, strong acids, and strong bases. For long-term storage, consider an inert atmosphere to maintain optimal stability.
