For professionals in the pharmaceutical industry, securing high-quality raw materials is paramount. One such critical compound is 4-oxo-1,4-dihydroquinoline-3-carboxylic acid (CAS 13721-01-2). This molecule serves as a vital intermediate, particularly in the synthesis of advanced therapeutics like HIV-1 integrase strand transfer inhibitors. If your organization is looking to buy 4-oxo-1,4-dihydroquinoline-3-carboxylic acid, understanding the sourcing process and what to look for in a manufacturer in China is key.

Understanding the Importance of Purity and Synthesis

The efficacy and safety of pharmaceutical products are directly linked to the quality of their constituent intermediates. Therefore, when sourcing 4-oxo-1,4-dihydroquinoline-3-carboxylic acid, purity is non-negotiable. Reputable suppliers will provide detailed certificates of analysis (COA) that specify the assay, typically aiming for ≥99.0% purity for pharmaceutical applications. The synthesis route is also important; a well-documented and optimized synthesis ensures consistency and minimizes the presence of unwanted by-products. For instance, a common synthesis involves the hydrolysis of ethyl 4-hydroxyquinoline-3-carboxylate, yielding the desired product as a light white solid with a high percentage yield.

Key Considerations When Selecting a Supplier

When you search for a CAS 13721-01-2 supplier, consider the following:

  • Manufacturing Capabilities: Does the supplier have robust manufacturing facilities and stringent quality control processes?
  • Regulatory Compliance: Look for suppliers adhering to international quality standards and providing necessary documentation.
  • Supply Chain Stability: Ensure they can meet your volume requirements consistently.
  • Technical Support: A good supplier offers technical assistance and responsive customer service.
  • Competitive Pricing: Obtaining a clear price quote is essential for budget management.

Partnering with a reliable pharmaceutical intermediate manufacturer in China can offer significant advantages in terms of cost-effectiveness and access to specialized chemical synthesis expertise.

The Role of 4-oxo-1,4-dihydroquinoline-3-carboxylic Acid in Drug Development
