Description

Undecanal is a high-purity, long-chain aliphatic aldehyde with a characteristic fatty, waxy, and citrus-like odor. It serves as a versatile and valuable fragrance intermediate and chemical building block for the synthesis of more complex aroma chemicals. This compound is essential for manufacturers in the flavor and fragrance, pharmaceutical intermediates, and specialty chemical industries seeking reliable quality and consistent supply.

Application

• Fragrance Ingredient: A key component in perfumery for creating citrus, floral, and waxy notes in fine fragrances, cosmetics, and personal care products.
• Flavoring Agent: Used in trace amounts to impart or enhance citrus and fatty nuances in food and beverage flavor formulations.
• Chemical Intermediate: Serves as a crucial starting material for the synthesis of other aldehydes, alcohols, acids, and their derivatives in organic chemistry.
• Aroma Chemical Production: Employed in the manufacturing of more complex fragrance compounds through reactions like aldol condensation or reduction.
• Research & Development: Utilized in academic and industrial R&D labs for studying reaction mechanisms and developing new synthetic pathways.

Quality Control

Our Undecanal is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC), to ensure it meets precise purity and identity specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature: 2-8°C.
