Description

4-Nonenal (Trans) is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct, powerful fatty and waxy odor profile. This compound is a key flavor and fragrance intermediate, prized for its ability to impart green, cucumber-like, and melon notes at low concentrations. It is essential for formulators and manufacturers in the flavor & fragrance and food ingredient industries seeking to create or enhance complex, natural-tasting profiles. The product is supplied under strict quality control to ensure consistency and performance in demanding applications.

Application

• Flavor & Fragrance (F&F) Industry: A crucial building block for creating and modifying flavor compositions, particularly for green, fatty, melon, and cucumber notes in beverages, dairy, and confectionery.
• Food Additives: Used as a flavoring agent to impart or enhance natural-tasting fatty and waxy nuances in processed foods and savory applications.
• Aroma Chemicals: Serves as a key intermediate in the synthesis of more complex aroma molecules and specialty fragrance compounds.
• Perfumery: Employed in fine fragrance and functional perfumery to add unique green and aldehydic top notes to sophisticated scent profiles.
• Research & Development: Used in academic and industrial R&D as a reference standard or starting material for organic synthesis and sensory studies.
• Cosmetic Ingredients: Incorporated into cosmetic formulations where specific, subtle fatty-green olfactory characteristics are desired.

Quality Control

Every batch of 4-Nonenal (Trans) is manufactured and tested to meet stringent internal specifications for identity, purity, and olfactory profile. Our quality assurance process includes rigorous analytical testing via GC, GC-MS, and IR spectroscopy to ensure chemical and isomeric purity. A comprehensive Certificate of Analysis (COA) detailing assay, physical properties, and impurity limits is provided with each shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C/59-77°F). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and open flame.
