For businesses operating in sectors reliant on specialized chemicals, understanding the global sourcing landscape is paramount. Difluorochloromethane, widely recognized as HCFC-22 or Freon 22, with CAS number 75-45-6, is one such compound with diverse industrial applications. As a discerning buyer, securing a reliable supply of this chemical is critical, and China has emerged as a significant manufacturing hub. This guide aims to provide insights into sourcing Difluorochloromethane from Chinese manufacturers and suppliers, focusing on aspects crucial for procurement managers and R&D scientists.

Understanding Difluorochloromethane (HCFC-22):

Difluorochloromethane is a colorless, nearly odorless gas. Chemically, it is known by formulas like CHClF2 and has a molecular weight of 86.47. Historically, it gained prominence as a refrigerant and aerosol propellant. However, its environmental impact, particularly its ozone-depleting potential and global warming potential, has led to regulatory phase-outs in many regions. Despite these regulations, HCFC-22 continues to be used as a chemical intermediate in the synthesis of other fluorinated compounds, such as tetrafluoroethylene polymers. For businesses still utilizing it for these purposes, securing a consistent supply is essential. If you are looking to buy Difluorochloromethane for industrial use, understanding its properties is the first step.

Key Considerations When Sourcing from China:

When you search for a Difluorochloromethane supplier China, several factors should guide your selection:

  • Quality and Purity: Look for manufacturers that provide detailed Certificates of Analysis (CoA) to confirm the purity and specifications of the HCFC-22. This is vital for R&D scientists and product formulators to ensure consistent performance and prevent downstream issues.
  • Manufacturing Capabilities: Ensure the manufacturer has robust production processes and can consistently meet your required volumes. The ability to supply large quantities reliably is a key indicator of a strong manufacturing partner.
  • Pricing and Cost-Effectiveness: Compare HCFC-22 price quotes from multiple suppliers. While cost is important, it should not be the sole deciding factor. Balance competitive pricing with quality and reliability. Negotiating the best price for chlorodifluoromethane often involves establishing long-term relationships.
  • Regulatory Compliance: Confirm that the supplier adheres to all relevant national and international regulations regarding the production, handling, and export of HCFC-22.
  • Logistics and Shipping: Understand the shipping capabilities, including port of departure (e.g., Shanghai port, Qingdao port), Incoterms (FOB, CFR, CIF), and delivery timelines. Efficient logistics are crucial for maintaining your production schedule.

Identifying Reputable Suppliers:

To find a dependable CAS 75-45-6 manufacturer, leverage industry directories, trade platforms, and professional networks. Look for companies with ISO certifications, a history of exporting, and positive customer testimonials. Direct engagement with potential suppliers, requesting samples, and clarifying all terms before placing an order are recommended steps for procurement managers. The goal is to establish a partnership with a manufacturer that prioritizes quality and service.

In conclusion, sourcing Difluorochloromethane from China can be a strategic move for businesses requiring this chemical intermediate. By carefully evaluating potential suppliers based on quality, capacity, pricing, and compliance, companies can secure a stable and cost-effective supply chain. Remember to always prioritize safety and regulatory adherence in all your chemical procurement activities.
