In the complex world of chemical procurement, identifying reliable sources for specialized intermediates is a constant challenge. 3-Bromo-5-methylbenzonitrile (CAS 124289-21-0) is one such compound, valued for its utility in organic synthesis and its specific structural attributes. This article serves as a practical guide for researchers and procurement professionals looking to source this critical chemical.

Understanding the Need for 3-Bromo-5-methylbenzonitrile

Before embarking on the search for a supplier, it's essential to understand why this particular compound is sought after. 3-Bromo-5-methylbenzonitrile is a key intermediate in the synthesis of various organic molecules. Its value lies in the presence of three distinct functional groups on an aromatic ring: a bromine atom, a methyl group, and a nitrile group. The bromine atom, in particular, is an excellent handle for cross-coupling reactions, allowing chemists to attach more complex molecular fragments and build sophisticated structures. This makes it invaluable in fields like pharmaceuticals, agrochemicals, and advanced materials research.

Key Considerations When Buying Online

When you decide to buy 3-Bromo-5-methylbenzonitrile, especially online, several factors are crucial to ensure you receive a quality product:

  • Supplier Reputation: Look for established chemical suppliers with a solid track record and positive reviews. Companies that specialize in intermediates for R&D are often a good starting point.
  • Product Specifications: Always verify that the product matches the CAS number (124289-21-0) and meets your required purity level (typically 97% or higher). Pay attention to the physical form (solid) and color (white to off-white).
  • Certificate of Analysis (CoA): A reputable supplier will readily provide a CoA for each batch, detailing analytical results for purity, identity, and impurity profiles.
  • Safety Data Sheet (SDS): Ensure an SDS is available, providing information on safe handling, storage, and potential hazards.
  • Packaging and Shipping: Inquire about packaging to ensure product integrity during transit and reliable shipping options.
  • Pricing: Compare prices from different suppliers, but always balance cost with quality and reliability. Bulk discounts are common for larger orders.

Finding a Reliable 3-Bromo-5-methylbenzonitrile Manufacturer in China

China has become a global powerhouse in chemical manufacturing, offering a vast array of specialized intermediates. For those looking to purchase 3-Bromo-5-methylbenzonitrile, Chinese manufacturers and suppliers are often the most competitive and accessible sources. Many companies excel in producing fine chemicals and intermediates, offering high-purity products at attractive price points.

When searching for a 3-Bromo-5-methylbenzonitrile supplier, consider companies that:

  • Specialize in organic synthesis intermediates.
  • Offer a wide range of related products.
  • Provide responsive customer service and technical support.
  • Have clear quality control procedures and readily available documentation (CoA, SDS).
  • Offer free samples for quality validation.

Many online platforms and chemical directories list numerous suppliers. However, it's prudent to cross-reference information and directly engage with potential partners to gauge their reliability and product quality. Companies like Alfa Chemistry, AK Sci, and others frequently appear as providers of this chemical.

Conclusion: Strategic Sourcing for Chemical Needs

Sourcing 3-Bromo-5-methylbenzonitrile requires diligence, but by focusing on product specifications, supplier reliability, and quality assurance, researchers and procurement managers can secure this essential intermediate. Whether for laboratory research or larger-scale production, a strategic approach to buying from trusted sources will ensure the success of your chemical synthesis projects.
