Description

Propyl Isocyanate is a versatile organic building block belonging to the isocyanate family, characterized by its highly reactive N=C=O functional group. This reactivity makes it a critical intermediate for synthesizing a wide range of valuable compounds, including pharmaceuticals, agrochemicals, and specialty polymers. Industries such as fine chemical manufacturing, crop protection, and polymer research rely on high-purity Propyl Isocyanate CAS NO 110-78-1 for its consistent performance in demanding synthetic applications.

Application

• Pharmaceutical Intermediate: Serves as a key reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing the propyl carbamoyl moiety.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides, where it acts as a precursor for ureas and carbamates.
• Polymer & Resin Modification: Employed to modify polyurethanes, coatings, and adhesives, enhancing properties like flexibility, adhesion, and chemical resistance.
• Organic Synthesis Reagent: A valuable building block for creating ureas, carbamates, and heterocyclic compounds in research and development laboratories.
• Crosslinking Agent: Functions as a crosslinker in specialty polymer systems to improve thermal stability and mechanical strength.
• Chemical Derivatization: Used in analytical chemistry to derivative compounds for improved detection and analysis via chromatography or spectrometry.

Quality Control

Our Propyl Isocyanate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, identity, and impurity profiles. Our quality systems are designed to meet the stringent requirements of GMP and ISO standards where applicable, supporting our commitment to supply reliability for critical B2B applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and moisture-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures between 2°C and 8°C for long-term stability. Keep away from strong bases and oxidizing agents.
