CAS 112-44-7: Undecanal
Description:Undecanal is an aliphatic aldehyde characterized by its straight-chain structure consisting of eleven carbon atoms. It is a colorless to pale yellow liquid at room temperature, with a distinctive fatty, waxy odor. Undecanal is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic nature. Its molecular formula is C11H22O, and it features a functional aldehyde group (-CHO) at one end of the carbon chain, which contributes to its reactivity and potential applications in organic synthesis. Undecanal is used in the production of fragrances and flavoring agents, as well as in the synthesis of various chemical compounds. Additionally, it can serve as a precursor in the manufacture of surfactants and other industrial chemicals. Due to its aldehyde functionality, undecanal can undergo typical reactions associated with aldehydes, including oxidation and condensation reactions. Safety precautions should be observed when handling undecanal, as it may cause irritation to the skin and eyes.
