Description

3-Decenal is a high-purity, unsaturated aliphatic aldehyde with the CAS registry number 58474-80-9, valued for its unique green, waxy, and citrus-like olfactory profile. This compound matters as a key flavor and fragrance intermediate, enabling the creation of complex, naturalistic sensory experiences in premium products. It is primarily needed by manufacturers in the flavor & fragrance (F&F) and food ingredient industries, as well as by research and development laboratories focusing on organic synthesis and aroma chemistry.

Application

• Flavor & Fragrance Formulation: A crucial building block for creating and enhancing green, citrus, melon, and waxy notes in perfumes, colognes, and fine fragrances.
• Food & Beverage Flavors: Used as a flavoring agent to impart fresh, cucumber-like, and fatty nuances to beverages, dairy products, and confectionery.
• Aroma Chemical Synthesis: Serves as a versatile intermediate in the synthesis of more complex aroma molecules and specialty chemicals.
• Personal Care Products: Incorporated into soaps, detergents, and cosmetics to provide a fresh, clean, and natural scent character.
• Research & Development: Utilized in academic and industrial R&D for studying organic reactions, particularly those involving α,β-unsaturated aldehydes.
• Tobacco Flavoring: Employed to modify and improve the sensory profile of tobacco products.

Quality Control

Our 3-Decenal is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and purity. We provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as assay, identity, and impurity profiles. While not a pharmaceutical active, our quality protocols are designed to meet the high standards of the flavor, fragrance, and food ingredient industries. Specifications and COAs are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and prevent degradation. Keep away from strong oxidizing agents, strong bases, and heat sources.
