For procurement managers and R&D scientists in the pharmaceutical and fine chemical sectors, sourcing high-quality raw materials is paramount. Among the essential building blocks, 4-Aminophthalic Anhydride (CAS 17395-99-2) stands out as a critical intermediate for Active Pharmaceutical Ingredient (API) synthesis. When you intend to buy this compound, understanding the key considerations for procurement can significantly impact the success of your downstream applications. This guide focuses on what to look for when sourcing this vital chemical from a reliable manufacturer.

Understanding the Importance of Purity

The purity of 4-Aminophthalic Anhydride directly influences the yield, quality, and safety of the final pharmaceutical product. Impurities can lead to unintended side reactions, reduced efficacy, and regulatory hurdles. Therefore, prioritizing suppliers who guarantee a high purity level, typically ≥99% for such critical intermediates, is non-negotiable. As a leading supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our 4-Aminophthalic Anhydride meets these exacting standards, providing you with a dependable product for your advanced organic synthesis needs.

Key Specifications to Verify Before Purchase

When you decide to purchase 4-Aminophthalic Anhydride, always verify crucial product specifications. Beyond purity, check for:

  • Molecular Formula and Weight: Confirm C8H5NO3 and its corresponding molecular weight for precise reaction calculations.
  • Synonyms: Be aware of common synonyms like 3-Aminophthalic anhydride or 4-Aminoisobenzofuran-1,3-dione to ensure you are referencing the correct substance.
  • Appearance: Typically supplied as a white powder, its physical form should be consistent.
  • CAS Number: 17395-99-2 is the definitive identifier.

These details are crucial for R&D scientists and formulators who rely on exact chemical properties for their work.

Choosing a Reliable Manufacturer and Supplier in China

The origin of your chemical supply chain is critical. When looking to buy 4-Aminophthalic Anhydride, partnering with an established manufacturer and supplier in China, like NINGBO INNO PHARMCHEM CO.,LTD., offers several advantages. These include competitive pricing, robust manufacturing capabilities, and a deep understanding of international chemical trade regulations. A trustworthy supplier will provide comprehensive product documentation, including Certificates of Analysis (CoA), and be transparent about their production processes. This reliability ensures that your production schedule remains on track and your research efforts are not compromised.

Inquiring about Price and Availability

For bulk orders or specific quotation requests, direct inquiry with the manufacturer is the most effective route. Understanding the pricing structure, minimum order quantities (MOQ), and lead times for delivery is essential for effective procurement planning. When you contact a supplier such as NINGBO INNO PHARMCHEM CO.,LTD. for 4-Aminophthalic Anhydride, be prepared to discuss your specific requirements, including desired quantities and delivery locations. This proactive approach helps in securing the best possible terms and ensuring a smooth purchasing experience for this key pharmaceutical intermediate.

By focusing on purity, verifying specifications, and partnering with a dependable supplier, your procurement of 4-Aminophthalic Anhydride will be a strategic step towards successful pharmaceutical development and fine chemical production.
