For researchers, chemists, and procurement specialists worldwide, the question of where to reliably buy high-quality 8-Hydroxyquinoline-2-Carboxylic Acid (CAS: 1571-30-8) is a constant consideration. As a valuable heterocyclic intermediate, its availability from reputable sources is key to successful projects across various industries, most notably pharmaceuticals and fine chemicals.

Understanding Market Availability

8-Hydroxyquinoline-2-Carboxylic Acid is a specialty chemical, and its sourcing often involves navigating a global network of manufacturers and distributors. While it can be found through various online chemical marketplaces and direct supplier websites, the critical factors remain purity, price, and reliability. Key sourcing regions include North America, Europe, and increasingly, Asia, with China being a prominent hub for chemical production. Identifying a trustworthy manufacturer or supplier is the first step in securing a consistent supply.

Key Sourcing Regions and Supplier Types

  • Chinese Manufacturers & Suppliers: Many global buyers turn to China for 8-Hydroxyquinoline-2-Carboxylic Acid due to competitive pricing and large-scale production capabilities. When you purchase from a supplier in China, it's crucial to look for established companies with strong quality control systems and export experience. They can often provide the best price for bulk orders.
  • European and North American Distributors: These suppliers often offer specialized services, smaller quantities suitable for research, and readily available documentation compliant with regional regulations. While potentially more expensive than direct sourcing from manufacturers, they can offer convenience and rapid delivery for urgent needs.
  • Online Chemical Marketplaces: Platforms like Alibaba, ChemicalBook, and others aggregate offerings from numerous suppliers. These can be a good starting point for identifying potential sources and comparing initial pricing, but thorough due diligence on individual suppliers is still required.

Factors to Consider When Buying

When you decide to buy 8-Hydroxyquinoline-2-Carboxylic Acid, consider these essential factors:

  • Purity: For most applications, 95% or 98% purity is standard. Always check the Certificate of Analysis (CoA) provided by the manufacturer.
  • Quantity: Determine whether you need gram-scale for R&D or kilogram/ton-scale for manufacturing. Pricing often varies significantly with volume.
  • Lead Time: Understand how long it will take for the product to be manufactured, packaged, and shipped to your location.
  • Technical Support: A good supplier will offer technical assistance and responsive customer service.
  • Safety Data: Ensure you receive the Material Safety Data Sheet (MSDS) for safe handling and storage.

Requesting Quotations and Samples

The most effective way to secure your supply is by directly contacting potential suppliers to request a quotation. This allows for direct discussion about your specific requirements and pricing. Many reputable companies also provide samples, enabling you to verify the quality before committing to a large purchase. By diligently researching and engaging with qualified chemical suppliers, you can confidently source the 8-Hydroxyquinoline-2-Carboxylic Acid needed for your critical applications.
