In the intricate world of chemical procurement, precise identification and reliable sourcing are paramount. For researchers and purchasing managers seeking 1-Chloroisoquinoline-4-carbonitrile, correctly referencing its CAS Number (53491-80-8) is the first step towards finding a dependable supplier. This article focuses on the importance of CAS numbers and how to effectively select Chinese manufacturers for this vital synthesis intermediate.

The Significance of CAS Numbers

The Chemical Abstracts Service (CAS) Registry Number is a unique numerical identifier for chemical substances. For 1-Chloroisoquinoline-4-carbonitrile, the CAS number 53491-80-8 is universally recognized and essential for unambiguous identification in databases, literature, and commercial transactions. When you search to buy this compound, using the correct CAS number ensures you are looking for the exact substance required for your synthesis or formulation needs.

Why Focus on Chinese Suppliers for 53491-80-8?

China's chemical manufacturing sector offers a broad spectrum of intermediates, including 1-Chloroisoquinoline-4-carbonitrile. Many Chinese manufacturers specialize in producing these compounds with high purity (typically 97% min) and at competitive prices. When sourcing a specific CAS number like 53491-80-8, partnering with a Chinese supplier can provide:

  • Access to a Wide Range of Manufacturers: A large number of producers means greater competition, potentially leading to better pricing and service.
  • Scalability: Chinese factories are often equipped for large-scale production, catering to both R&D quantities and commercial demands.
  • Cost-Effectiveness: Manufacturing efficiencies in China frequently translate to more affordable prices for intermediates.

Selecting a Reputable Supplier

When you decide to buy 1-Chloroisoquinoline-4-carbonitrile, selecting the right supplier is key to ensuring quality and reliability. Here are some tips:

  1. Verify the CAS Number: Double-check that the supplier lists 53491-80-8 accurately for 1-Chloroisoquinoline-4-carbonitrile.
  2. Confirm Purity: Ensure they offer the required purity, typically 97% minimum.
  3. Request Samples: Always ask for a free sample to evaluate the quality before placing a large order.
  4. Check for Certifications and Documentation: Reputable suppliers will provide Certificates of Analysis (CoA) and relevant safety data sheets (SDS).
  5. Read Reviews and Testimonials: Look for feedback from other buyers to gauge supplier reliability.
  6. Communicate Clearly: Discuss your specific needs, quantity requirements, and delivery expectations.

By focusing on the correct CAS number and adopting a diligent approach to supplier selection, procurement professionals can confidently source 1-Chloroisoquinoline-4-carbonitrile (CAS: 53491-80-8) from China, ensuring the quality and consistency needed for their critical chemical synthesis projects.
