Hexadecanal（Cat No.:R047296）, also known as palmitic aldehyde, is a long-chain aliphatic aldehyde with the molecular formula C₁₆H₃₂O. It consists of a 16-carbon saturated hydrocarbon chain terminating in an aldehyde group. Hexadecanal is a white, waxy solid at room temperature and is slightly soluble in water but readily soluble in organic solvents. It occurs naturally in some plant oils and animal tissues and plays a role in chemical signaling, including pheromone activity in insects. In industrial and research settings, it is used in the synthesis of surfactants, fragrances, and lipid-related compounds.
