Pentadecyl isocyanate
Pentadecyl isocyanate (CAS 39633-51-7, C16H31NO) is an organic compound featuring a long alkyl chain and a reactive isocyanate group. With a molecular weight of 253.42 g/mol, it functions as a versatile building block in organic synthesis. Its primary applications include the introduction of the pentadecyl moiety into larger molecules, facilitating the creation of specialised polymers and functional materials.

Organic Synthesis Intermediate
Pentadecyl isocyanate serves as a key intermediate in the synthesis of complex organic molecules. The reactive isocyanate group readily undergoes addition reactions with nucleophiles like alcohols and amines.
Polymer Modification
This compound can be used to modify polymers, introducing long alkyl chains to alter material properties such as hydrophobicity and flexibility. It is valuable in the development of specialised coatings and materials.
Surfactant Synthesis
The long hydrophobic pentadecyl chain makes this isocyanate a potential precursor for specialised surfactants and emulsifying agents. Reaction with hydrophilic groups can yield amphiphilic molecules.
