For procurement specialists in the chemical and pharmaceutical industries, understanding the nuances of sourcing critical intermediates like 2,4-Dinitrofluorobenzene (CAS 70-34-8) is vital. This compound, a key pharmaceutical intermediate, demands careful consideration when you plan to buy it. This guide aims to equip buyers with the knowledge to make informed decisions, whether you're a research scientist or a supply chain manager.

Understanding Product Specifications

When sourcing 2,4-Dinitrofluorobenzene, pay close attention to key specifications:

  • Appearance: Light yellow crystal. This visual cue is a primary indicator of product quality.
  • Assay (Purity): A minimum of ≥99.0% is typically required for pharmaceutical synthesis to ensure the integrity of downstream processes and final APIs.
  • CAS Number: 70-34-8 is the definitive identifier.
  • Impurities: Low levels of related compounds like 2-nitrofluorobenzene and 4-nitrofluorobenzene (≤0.10% each) are critical for high-purity applications.
  • Packaging: Standard packaging is often 25kg/drum, but confirm if custom packaging is available to meet your specific needs.

Key Applications to Consider

The primary driver for purchasing 2,4-Dinitrofluorobenzene is its role in synthesizing essential pharmaceuticals, most notably fluoroquinolone antibiotics:

  • Ciprofloxacin: A widely used antibiotic, its synthesis relies heavily on this intermediate.
  • Difloxacin & Pefloxacin: Other important antibiotics that utilize 2,4-Dinitrofluorobenzene in their production pathways.

Knowing these applications helps procurement professionals assess the quality requirements and the importance of securing a reliable supplier.

Sourcing Strategies and Vendor Selection

When evaluating where to purchase dinitrofluorobenzene, consider the following:

  • Manufacturer vs. Distributor: Direct purchasing from a manufacturer often provides better control over quality and pricing.
  • Geographic Location: Exploring reputable 2,4-dinitrofluorobenzene suppliers in China can offer competitive pricing and significant volume capabilities.
  • Price Negotiation: Understanding the market price of 1-fluoro-2,4-dinitrobenzene for synthesis allows for informed negotiation.
  • Due Diligence: Always request Certificates of Analysis (CoA) and review the supplier’s credentials and customer feedback.

Securing a reliable source for 2,4-Dinitrofluorobenzene involves a thorough understanding of the product's specifications, its critical role in pharmaceutical manufacturing, and a strategic approach to supplier selection. By partnering with a quality-focused CAS 70-34-8 manufacturer, you ensure the continuity and quality of your production pipeline.
