As a leading manufacturer and supplier in China, we understand the challenges B2B procurement managers and R&D scientists face when sourcing this vital compound. This article aims to guide you through the process of identifying and purchasing 4-Chlorophenyl Isocyanate with confidence.

Understanding 4-Chlorophenyl Isocyanate (CAS 104-12-1)

4-Chlorophenyl Isocyanate is a reactive organic compound valued for its isocyanate functional group, which readily participates in addition reactions. Its molecular formula is C7H4ClNO, with a molecular weight of 153.57. Typically appearing as a white to yellow crystalline solid, it has a melting point between 26-29 °C and a boiling point of 203-204 °C. Its sensitivity to moisture and lachrymatory properties necessitate careful handling and storage, usually at 2-8°C.

Key Applications in Industry

The versatility of 4-Chlorophenyl Isocyanate makes it indispensable in several key industries:

  • Pharmaceutical Synthesis: It serves as a critical intermediate in the synthesis of various pharmaceutical compounds. Notably, it's used in the creation of novel pyrimido[5,4-c]quinolin-4(3H)-one derivatives, which have demonstrated promising antibacterial, antifungal, and even anti-tumor properties. For R&D scientists looking to develop new therapeutic agents, reliable access to this compound is essential.
  • Agrochemicals: In the agrochemical sector, 4-Chlorophenyl Isocyanate is a building block for producing pesticides and other crop protection agents. Its structure contributes to the efficacy of these products, aiding in pest control and improving agricultural yields. Procurement managers seeking cost-effective raw materials will find value in sourcing this intermediate.
  • Organic Synthesis: Beyond these specific sectors, it's a valuable reagent in broader organic synthesis, enabling the creation of diverse chemical structures and advanced materials.

Sourcing from China: What Buyers Need to Know

When you decide to buy 4-Chlorophenyl Isocyanate, sourcing from China offers significant advantages, particularly in terms of competitive pricing and robust manufacturing capabilities. However, it's crucial to partner with reputable suppliers. Here’s what to look for:

  • Manufacturer vs. Distributor: Opting for a direct manufacturer like ourselves ensures better control over quality, pricing, and supply chain stability. We are a primary supplier of 4-Chlorophenyl Isocyanate in China.
  • Quality Assurance: Verify that the supplier provides detailed specifications, Certificates of Analysis (CoA), and MSDS for their product. Consistent purity (e.g., 97% Min.) is key for predictable results in your synthesis.
  • Supply Capacity and Lead Times: For large-scale manufacturing, confirm the supplier's production capacity (we offer 100 Tons productivity) and inquire about lead times for bulk orders. As a consistent supplier, we cater to both R&D and industrial quantities.
  • Pricing and Payment Terms: Obtain quotes for your required quantities. Manufacturers typically offer more competitive pricing for larger volumes. Understand their payment terms (L/C, T/T, etc.) and Incoterms (FOB, CFR, CIF).
  • Logistics and Export: Ensure the supplier has experience with international shipping and can handle the complexities of exporting chemicals, including proper packaging and documentation for transport via ocean, land, or air.
