For procurement professionals in the chemical and pharmaceutical industries, sourcing specialized intermediates like 3-Bromo-5-methylbenzonitrile (CAS 124289-21-0) requires a strategic approach. This compound, a vital building block in organic synthesis, demands careful consideration of quality, purity, and supplier reliability. This guide aims to equip you with the knowledge to efficiently source this essential chemical.

Key Specifications to Prioritize

When you intend to buy 3-Bromo-5-methylbenzonitrile, understanding its critical specifications is the first step. The core details you should look for include:

  • CAS Number: 124289-21-0 – this unique identifier ensures you are procuring the correct chemical compound.
  • Molecular Formula: C8H6BrN – confirms the atomic composition.
  • Molecular Weight: 196.04 – essential for stoichiometric calculations.
  • Purity: Most commonly offered at 95% or 97%. Higher purity is often preferred for sensitive syntheses to minimize side reactions and ensure product integrity.
  • Physical Form: Typically a solid, described as white to off-white.
  • Melting Point: Ranges around 57-73°C, depending on the purity and supplier.
  • Boiling Point: Around 256.1±20.0℃, indicating its thermal stability under specific conditions.

Ensuring Quality and Reliability

Quality assurance is non-negotiable when procuring chemical raw materials. As a 3-Bromo-5-methylbenzonitrile manufacturer or supplier, particularly from China, providing comprehensive documentation is key. Always request a Certificate of Analysis (CoA) for each batch. This document should detail the analytical methods used (e.g., NMR, GC-MS) and confirm that the product meets the stated specifications, including purity, appearance, and impurity profiles.

Furthermore, inquire about the supplier's manufacturing standards and quality control processes. Established manufacturers will have robust quality management systems in place. Consider suppliers who offer free samples; this allows your R&D team to validate the product's suitability for your specific applications before placing larger orders. A responsive supplier who can provide timely technical support is also invaluable.

Finding Trusted Suppliers in China

China is a dominant force in global chemical production, offering a wide range of intermediates like 3-Bromo-5-methylbenzonitrile. When seeking a 3-Bromo-5-methylbenzonitrile supplier in China, look for established companies with a proven track record. Many leading chemical distributors and manufacturers have dedicated export departments to serve international clients.

Key considerations when selecting a supplier:

  • Experience: Look for suppliers with years of experience in chemical manufacturing and export.
  • Product Range: A supplier offering a broad portfolio of organic intermediates may indicate a more robust operational capacity.
  • Customer Reviews and Testimonials: Research feedback from other international buyers.
  • Communication: Clear and prompt communication is vital for successful international transactions.
  • Pricing: Compare quotes from multiple suppliers, keeping in mind that the lowest price isn't always indicative of the best value. Factor in quality, reliability, and lead times.

The Purchasing Process: From Inquiry to Delivery

When you are ready to purchase 3-Bromo-5-methylbenzonitrile, initiate contact with your chosen supplier. Clearly state your requirements: CAS number, purity, quantity, and desired delivery timeline. Be prepared to provide your company's details for verification, as many suppliers have onboarding processes for new customers.

Negotiate pricing, payment terms, and shipping arrangements. Understand Incoterms to clarify responsibilities regarding shipping, insurance, and customs clearance. For large quantities, inquire about bulk discounts and suitable packaging to ensure product integrity during transit.

By following these guidelines, procurement professionals can effectively source high-quality 3-Bromo-5-methylbenzonitrile, ensuring the success of their critical research and production projects. Partnering with reliable manufacturers from China can offer significant advantages in terms of cost and availability.
