Product Description:

2-Undecanone, also known as methyl nonyl ketone, is a methyl ketone with the molecular formula C11H22O. It is a colorless to pale yellow liquid with a characteristic fruity, waxy, and slightly fatty odor reminiscent of rue oil. Its primary and most significant application is as a fragrance ingredient and flavoring agent. It is widely used in the formulation of perfumes, cosmetics, soaps, and detergents to impart fruity, waxy, and creamy notes. It is also employed in food flavorings for dairy products, fruits, and nuts. Beyond its organoleptic uses, 2-undecanone is recognized for its insect repellent properties, particularly against ticks, mosquitoes, and other arthropods, and is sometimes used in related applications. As a simple aliphatic methyl ketone, it serves as a versatile organic synthetic building block in chemical synthesis, particularly in aldol condensation reactions and as a precursor for other derivatives. It is generally considered to have low acute toxicity but should be handled with standard laboratory precautions.
