For any chemist or procurement manager involved in advanced organic synthesis, the selection of starting materials significantly impacts the success of their projects. 4-Bromo-3-chlorobenzonitrile (CAS 57418-97-0) is a critical intermediate widely used in pharmaceutical and fine chemical manufacturing. This guide focuses on how to strategically purchase this compound, ensuring you obtain the best quality and value from reputable suppliers, particularly those in China.

Key Attributes of 4-Bromo-3-chlorobenzonitrile

Before initiating a purchase, understanding the product's specifications is vital. 4-Bromo-3-chlorobenzonitrile (C7H3BrClN, MW: 216.46) is typically supplied as an off-white crystalline solid. Critical specifications include:

  • Purity: Commonly available at 97% or 98% minimum purity. For sensitive applications like pharmaceutical intermediate synthesis, higher purity is often preferred.
  • Physical Form: As a crystalline solid, it is generally stable and easier to handle compared to liquids.
  • CAS Number: 57418-97-0 – this unique identifier is crucial for accurate ordering.
  • Melting Point: Usually in the range of 80-81°C, a key indicator of purity.

Strategies for Effective Purchasing

When you need to buy 4-Bromo-3-chlorobenzonitrile, a strategic approach to sourcing can save time and resources:

  1. Identify Reputable Manufacturers: Look for established chemical companies, especially those with a strong presence in China, known for their quality control and production capabilities. These suppliers often offer competitive pricing for bulk orders.
  2. Request Detailed Quotes: When reaching out for a quote, be specific about your required quantity, purity, and any specific analytical documentation needed (e.g., CoA, MSDS).
  3. Evaluate Supplier Reliability: Check for customer reviews, certifications, and the supplier's history. A reliable supplier will provide consistent product quality and timely delivery.
  4. Consider Packaging and Shipping: Ensure the packaging is appropriate for the chemical's stability and that shipping methods comply with regulations for chemical transport.
  5. Inquire About Samples: Always request a sample for testing in your laboratory before placing a large order to confirm its suitability for your specific synthesis.
