For chemists, researchers, and procurement specialists working with fine chemicals, a thorough understanding of a compound's properties is fundamental. 1-Naphthyl Isocyanate, identified by its CAS number 86-84-0, is a chemical intermediate with specific characteristics that dictate its handling, storage, and application. This article provides an overview of its key physical and chemical properties, offering valuable insights for anyone looking to buy or use this substance.

1-Naphthyl Isocyanate, with the molecular formula C11H7NO and a molecular weight of 169.18 g/mol, typically appears as a colorless to light yellow liquid. Its physical properties are critical for process design and safety. The melting point is reported to be around 4-7 °C, indicating that it is a liquid at standard room temperatures. Its boiling point is approximately 80.7 °C at reduced pressure (lit.), and a higher value of 269°C at atmospheric pressure is also noted, though this can vary.

The density of 1-Naphthyl Isocyanate is approximately 1.177 g/mL at 25 °C, and its refractive index is around n20/D 1.6344. These parameters are important for quality control and identification purposes when purchasing from a supplier.

Solubility is another key characteristic. 1-Naphthyl Isocyanate is miscible with common organic solvents such as alcohol, chloroform, and diethyl ether. This solubility profile makes it adaptable to various reaction conditions and formulations.

However, it's crucial to note that 1-Naphthyl Isocyanate is sensitive to moisture. The isocyanate group (-NCO) is highly reactive and readily reacts with water, leading to the formation of amines and carbon dioxide, or potentially ureas. This moisture sensitivity necessitates careful handling and storage. Suppliers typically package it in tightly sealed containers, and it is recommended to store it at cool temperatures (0-10°C) to maintain its stability and reactivity for purchase.

Additionally, 1-Naphthyl Isocyanate is incompatible with strong oxidizing agents and alcohols. Proper storage and handling protocols, as outlined in the Material Safety Data Sheet (MSDS), should be strictly followed to prevent hazardous reactions. When you buy 1-Naphthyl Isocyanate, always consult the manufacturer's guidelines for optimal usage.
