Description

2-Ethylundecanal is a high-purity, branched-chain aliphatic aldehyde with a distinctive, powerful, and waxy-floral odor profile. This compound matters as a versatile and valuable fragrance intermediate, prized for its ability to impart unique olfactory characteristics and enhance the complexity of scent formulations. Manufacturers in the flavor and fragrance industry, as well as producers of fine chemicals and specialty surfactants, rely on its consistent quality for their premium product lines.

Application

• Fragrance Compound Synthesis: A key building block for creating novel musk, floral, and fruity aroma chemicals.
• Perfumery: Used as a mid-to-base note in fine perfumes, soaps, detergents, and cosmetic products for its long-lasting, waxy character.
• Flavor Enhancement: Employed in trace amounts to create or modify citrus, fruity, and fatty flavor nuances.
• Chemical Intermediate: Serves as a precursor in organic synthesis for pharmaceuticals, agrochemicals, and specialty polymers.
• Surfactant and Lubricant Additives: Utilized in the modification of surfactants and the synthesis of lubricant additives.
• Research & Development: A valuable reagent for academic and industrial R&D in organic chemistry and material science.

Quality Control

Our 2-Ethylundecanal is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing, including GC and IR analysis, to ensure it meets the high standards required for fragrance and synthesis applications. A Certificate of Analysis (COA) detailing purity, identity, and physical parameters is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal purity and shelf life. Keep away from strong oxidizing agents, acids, and bases.
