Description

Octadecanal delivers a long-chain aliphatic aldehyde functionality ideal for lipid-based synthesis and functional material design. This saturated C18 aldehyde exhibits excellent stability under standard conditions, enabling reliable incorporation into complex molecular architectures. Its terminal aldehyde group facilitates selective derivatization in conjugation chemistries and surface modification applications.

Application

Octadecanal serves as a long-chain aliphatic aldehyde enabling efficient synthesis of esters, imines, and α,β-unsaturated systems via standard carbonyl reactions. Its extended alkyl chain provides enhanced solubility in nonpolar media and contributes to improved stability under ambient conditions. Widely employed in lipid chemistry and surfactant derivatization, it facilitates clean functionalization with minimal side-product formation, making it well-suited for bench-scale applications requiring predictable reactivity and straightforward purification.
