Octadecyl Isocyanate, identified by its CAS number 112-96-9, is a significant organic chemical that plays a crucial role as an intermediate in numerous synthesis pathways. Its unique molecular structure combines a reactive isocyanate group (-NCO) with a long, hydrophobic eighteen-carbon alkyl chain (octadecyl), making it a versatile compound for various industrial applications.

The physical and chemical properties of Octadecyl Isocyanate are key to its utility. It typically presents as a colorless to slightly turbid liquid with a purity level often exceeding 99%. Its molecular formula is C19H37NO, and it has a molecular weight of approximately 295.57 g/mol. The presence of the isocyanate group renders it highly reactive towards compounds containing active hydrogen atoms, such as alcohols, amines, and water. These reactions lead to the formation of valuable derivatives like carbamates, ureas, and polyurethanes, respectively. The long octadecyl chain influences the solubility, viscosity, and surface properties of the resulting products.

For businesses aiming to buy Octadecyl Isocyanate, identifying a reliable supplier is paramount. China has emerged as a major hub for chemical manufacturing, offering a robust supply of fine chemicals and intermediates. When seeking an Octadecyl Isocyanate supplier, it is advisable to look for manufacturers with a strong reputation for quality, consistency, and ethical business practices. Companies that provide detailed product specifications, adhere to international quality standards, and offer competitive pricing are typically preferred.

The applications of Octadecyl Isocyanate span across several sectors. In material science, it's used for surface modification to impart hydrophobicity or to create self-assembled monolayers. It also serves as a building block for polymers and specialty coatings where its long alkyl chain can influence flexibility and compatibility. In organic synthesis, it's a critical intermediate for creating complex molecules, including those with pharmaceutical or agrochemical relevance. Therefore, ensuring a stable and high-quality supply of Octadecyl Isocyanate (CAS 112-96-9) from trusted Chinese manufacturers is essential for sustained innovation and production.
