Description

4-Nonenal is a high-purity, unsaturated aliphatic aldehyde with the CAS registry number 37423-42-0. This compound is valued for its potent, characteristic fatty and cucumber-like odor, making it a crucial flavor and fragrance intermediate. It is primarily sought after by manufacturers in the flavor & fragrance (F&F), food ingredient, and fine chemical synthesis industries for creating complex organoleptic profiles and advanced chemical building blocks.

Application

• Flavor & Fragrance Formulation: A key aroma chemical used to impart fresh, green, fatty, and cucumber-like notes in perfumes, cosmetics, and personal care products.
• Food Flavoring: Employed as a flavor enhancer in processed foods, beverages, and savory applications to create natural-tasting fatty and melon nuances.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis, particularly in the production of more complex aldehydes, alcohols, and other derivatives for pharmaceutical and agrochemical research.
• Aroma Chemical Production: Used in the manufacturing of other high-value aroma chemicals and fragrance accords.
• Research & Development: Utilized in analytical laboratories and R&D facilities as a reference standard and for studying lipid oxidation products and flavor chemistry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, it is recommended to keep the container under an inert gas (e.g., nitrogen) and minimize exposure to air and light during handling.
