Butyl Isocyanate, scientifically known as n-Butyl Isocyanate (CAS: 111-36-4), is a foundational chemical intermediate with a broad spectrum of applications across various industries. Its unique reactivity profile makes it a valuable component in numerous synthesis processes, from pharmaceuticals to advanced materials.

The chemical structure of n-Butyl Isocyanate features a reactive isocyanate group (-N=C=O) attached to a four-carbon butyl chain. This group is highly susceptible to nucleophilic attack, enabling it to readily form covalent bonds with molecules containing active hydrogen atoms. This characteristic is fundamental to its use in creating urethane and urea linkages, which are prevalent in many end products. Typically appearing as a colorless to pale yellow transparent liquid, the compound is specified with a high purity of ≥99.0%. Key physical properties include a boiling point of 115.0±0.0 °C at 760 mmHg and a flash point of 17.8±0.0 °C, critical data points for safe handling and process implementation.

The applications of n-Butyl Isocyanate are diverse. In the pharmaceutical sector, it serves as a building block for synthesizing active pharmaceutical ingredients (APIs) and intermediates. In the agrochemical industry, it is used in the production of pesticides and herbicides. Beyond these, it finds utility in the creation of specialty polymers, coatings, and adhesives, where its ability to form strong linkages is highly valued. Researchers and manufacturers seeking to purchase this chemical often look for 'butyl isocyanate price' and inquire about it from reliable sources.

When considering procurement, identifying a dependable manufacturer is key. Many industry professionals look to source chemicals from manufacturers in China due to competitive pricing and established supply chains. Whether you are looking to 'buy n-butyl isocyanate' for research or large-scale production, ensuring product consistency, availability in standard packaging like 200 kg/drum, and responsive customer service are vital considerations.

In essence, n-Butyl Isocyanate is a versatile and essential chemical intermediate. Its well-defined properties and broad applicability make it a go-to compound for many synthetic chemists and production managers. For those in need of this critical chemical, understanding where to buy and from whom will ensure the quality and efficiency of their operations.
