For professionals in the pharmaceutical and diagnostic sectors, sourcing high-quality chemical intermediates is paramount. Among these, 4-Aminohippuric Acid (CAS 61-78-9) stands out for its critical role in renal function testing and as a versatile research compound. As a prominent manufacturer and supplier based in China, we understand the stringent requirements of B2B procurement for such specialized chemicals. This guide aims to equip you with the knowledge to effectively source 4-Aminohippuric Acid and ensure product integrity for your applications.

Understanding 4-Aminohippuric Acid's Importance

Also known as p-Aminohippuric Acid (PAH), this compound is primarily utilized for its ability to measure effective renal plasma flow (ERPF). Its unique pharmacokinetic profile, where it is almost completely cleared by the kidneys in a single pass, makes it an ideal marker for assessing kidney function and detecting potential disorders. Beyond diagnostics, it serves as a valuable tool in nephrology and pharmacology research, particularly in studies involving organic anion transporters (OATs) and drug interaction assessments. When you buy 4-Aminohippuric Acid, you are investing in a compound that directly impacts the accuracy of critical medical evaluations and the advancement of renal research.

Key Considerations When Sourcing from China Manufacturers

When looking to purchase 4-Aminohippuric Acid, especially from Chinese suppliers, several factors are crucial for ensuring a successful transaction and receiving a product that meets your specifications:

  • Purity Levels: Always prioritize products with high purity, typically exceeding 98%. This ensures accurate results in diagnostic tests and reliable outcomes in synthesis. Verify that the Certificate of Analysis (CoA) from the manufacturer clearly states the purity and analytical methods used.
  • CAS Number Verification: Confirm that the CAS number is indeed 61-78-9. This unique identifier ensures you are procuring the correct chemical entity.
  • Supplier Reputation and Reliability: Research potential suppliers. Look for companies with established export experience, adherence to international quality standards (like ISO certifications), and positive customer feedback. Companies that openly share product specifications and offer technical support are generally more reliable.
  • Packaging and Storage: Understand how the product is packaged and its recommended storage conditions. Proper packaging, such as airtight containers, is essential for maintaining product stability and preventing degradation during transit and storage.
  • Pricing and Bulk Discounts: Obtain quotes from multiple manufacturers to compare prices. Be aware that significant price variations might indicate differences in purity, production scale, or quality control. Inquire about bulk discounts for larger orders, which is common practice when you buy pharmaceutical intermediates in significant quantities.
  • Lead Times and Logistics: Clarify lead times for production and shipping. Experienced suppliers will provide realistic estimates and transparent shipping information, including Incoterms (e.g., FOB, CFR) and port of origin.
