Hexadecyl isocyanate
Hexadecyl isocyanate (CAS: 1943-84-6), with the linear formula CH3(CH2)15NCO and a molecular weight of 267.45 g/mol, is a long-chain alkyl isocyanate. It serves as a valuable reagent in organic synthesis, particularly for introducing the hexadecyl group onto various molecules. Its chemical reactivity makes it useful in the development of specialised polymers and functionalised materials.
Organic Synthesis Reagent
Hexadecyl isocyanate is employed as a building block in organic synthesis to introduce the C16 alkyl chain. It reacts readily with nucleophiles such as alcohols, amines, and water to form urethanes, ureas, and carbamic acids, respectively.
Polymer Modification
This isocyanate can be used to functionalise polymers, imparting properties such as hydrophobicity or altered solubility. It is also a potential monomer or co-monomer in the synthesis of specific polyurethanes.
Surface Chemistry
The long alkyl chain of hexadecyl isocyanate makes it suitable for modifying surfaces to create hydrophobic or self-assembled monolayers. Such modifications are useful in material science and nanotechnology applications.
