Understanding Bis(4-nitrophenyl) Carbonate (CAS 5070-13-3)

Bis(4-nitrophenyl) Carbonate, with its molecular formula C13H8N2O7 and CAS number 5070-13-3, is a crystalline solid, typically appearing as off-white to light-yellow crystals. Its molecular weight is 304.21. The primary utility of this compound lies in its reactivity, making it an excellent reagent for specific synthetic pathways. Its role as a precursor in the synthesis of amino acid 4-nitrophenyl active esters is particularly significant for peptide chemistry and drug discovery. Furthermore, it is widely employed in the preparation of various ureas, compounds that find broad applications across pharmaceuticals, agrochemicals, and materials science.

Key Considerations When Buying Bis(4-nitrophenyl) Carbonate

When you need to buy Bis(4-nitrophenyl) Carbonate, several factors must be carefully evaluated:

  • Purity: The assay specification, typically ≥98.5% via HPLC, is critical. High purity ensures predictable reaction outcomes and minimizes unwanted by-products, which is essential for sensitive applications. A reliable manufacturer will always provide detailed Certificates of Analysis (CoA) confirming purity.
  • Appearance: While seemingly minor, the consistent appearance of off-white to light-yellow crystals is an indicator of well-controlled manufacturing processes.
  • Capacity and Supply Stability: For industrial-scale production, securing a supplier with sufficient monthly capacity (e.g., 1 mt) and a history of reliable delivery is crucial. Supply chain disruptions can significantly impact production schedules and costs.
  • Pricing: When requesting a quote for Bis(4-nitrophenyl) Carbonate, consider the overall value, not just the per-kilogram price. Factors like purity, packaging, and logistical support contribute to the total cost of ownership.
  • Application Suitability: Ensure the grade and specifications of the Bis(4-nitrophenyl) Carbonate you are purchasing align perfectly with your intended use, whether for research and development or large-scale manufacturing of urea synthesis intermediates.

Why Choose a Dedicated Manufacturer?

Partnering with a dedicated manufacturer of Bis(4-nitrophenyl) Carbonate offers several advantages. Manufacturers have direct control over the production process, ensuring consistent quality and adherence to specifications. They are often more adept at providing technical support and can offer competitive pricing, especially for bulk purchases. When sourcing from China, look for established chemical companies that have a proven track record in producing fine chemical intermediates.

For example, a reputable supplier will offer Bis(4-nitrophenyl) Carbonate in standard packaging like 25 kg fiber drums, suitable for both laboratory and industrial use. They should also be responsive to inquiries regarding samples, delivery times, and custom orders.

Conclusion: Your Strategic Partner for Chemical Procurement

Sourcing Bis(4-nitrophenyl) Carbonate requires diligence. By focusing on purity, understanding its applications in urea synthesis and active ester formation, and identifying reliable manufacturers and suppliers, procurement managers and R&D scientists can ensure the success of their projects. If you are looking to purchase high-quality Bis(4-nitrophenyl) Carbonate, seeking a quote from an experienced supplier in China can provide you with the reliable materials and competitive pricing needed to drive your innovations forward.
