n-Butyl Isocyanate, with its CAS number 111-36-4, is a fundamental chemical intermediate that warrants a closer look for professionals within the chemical industry. Its unique chemical structure dictates its utility, while market dynamics influence its availability and pricing.

The core of n-Butyl Isocyanate's chemical identity lies in the highly reactive isocyanate group (-N=C=O) attached to a butyl chain. This functional group readily participates in addition reactions, particularly with compounds containing active hydrogen atoms like alcohols, amines, and water. This reactivity is key to its widespread use in forming polymers, pharmaceuticals, and agrochemicals. As a colorless to pale yellow transparent liquid, it typically boasts a purity of ≥99.0%, a critical factor for precise synthetic outcomes. Its boiling point of 115.0±0.0 °C and flash point of 17.8±0.0 °C are important safety and process parameters that users must consider when handling or purchasing this chemical.

From a market perspective, the demand for n-Butyl Isocyanate is closely tied to the growth of industries such as pharmaceuticals, agriculture, and materials science. Companies seeking to buy this intermediate often look for manufacturers that can offer not only competitive 'n-butyl isocyanate price' but also consistent quality and reliable delivery. Sourcing from established manufacturers, particularly those with a strong presence in China, can provide access to cost efficiencies and a stable supply chain. For many, the search begins with phrases like 'where to buy n-butyl isocyanate' or 'n-butyl isocyanate manufacturer'.'

Understanding the packaging, such as the standard 200 kg/drum, and the logistical capabilities of suppliers is also crucial for effective procurement. Building relationships with trusted suppliers ensures that you not only secure the necessary quantities but also maintain the high standards required for your production processes. The availability of samples and detailed product specifications from manufacturers further aids in the decision-making process.

In summary, n-Butyl Isocyanate is a vital chemical with well-defined properties and broad applications. For industry professionals, a comprehensive understanding of its chemistry and the market landscape, including reliable sourcing channels and pricing considerations, is essential for successful procurement and utilization.
