Dodecyl Isocyanate (CAS 4202-38-4) is a valuable organic chemical intermediate used in various synthetic processes. For professionals in the chemical and pharmaceutical sectors, understanding its characteristics, proper handling procedures, and how to source it effectively is crucial for successful operations. This guide provides insights into the properties, safety considerations, and sourcing strategies for Dodecyl Isocyanate.

Key Properties of Dodecyl Isocyanate

Dodecyl Isocyanate, also known by synonyms like Lauryl Isocyanate, is characterized by its molecular formula C13H25NO and a CAS number of 4202-38-4. Its physical appearance is typically a colorless to light yellow liquid. A critical quality parameter is its purity, which is generally specified at a minimum of 98.00% by gas chromatography (GC). The compound's refractive index is often cited around n20/D 1.441. Due to the reactive nature of the isocyanate group, Dodecyl Isocyanate is sensitive to moisture and requires careful storage, usually at 0-10°C or 4°C, to maintain its integrity and reactivity.

Safe Handling and Storage

As with all isocyanates, Dodecyl Isocyanate necessitates stringent safety protocols. It is classified as a hazardous material, with potential risks including irritation to skin, eyes, and respiratory tract, and the possibility of sensitization. Precautionary statements often include ensuring adequate ventilation, wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and respiratory protection, and avoiding contact with skin and eyes. Due to its moisture sensitivity, it should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from incompatible materials like water, alcohols, and amines.

Sourcing Dodecyl Isocyanate

For companies looking to buy Dodecyl Isocyanate, identifying reliable manufacturers and suppliers is paramount. Leading chemical producers, particularly those based in China, offer this compound at competitive prices with guaranteed quality. When inquiring about Dodecyl Isocyanate, it's important to request a Certificate of Analysis (CoA) to verify purity and other specifications, as well as a Safety Data Sheet (SDS) for comprehensive handling information. Procurement managers often compare pricing from multiple sources to secure the best value for bulk purchases. Establishing a relationship with a trusted supplier ensures a consistent and dependable source of this important chemical intermediate for ongoing production and research needs.
