For pharmaceutical manufacturers involved in the synthesis of life-saving drugs like Gefitinib, the quality and availability of key intermediates are paramount. 6,7-Dimethoxyquinazoline-4-one (CAS: 13794-72-4) stands as a critical building block in this complex process. Understanding the requirements for sourcing this vital compound is essential for ensuring efficient production runs and the ultimate efficacy of the final Active Pharmaceutical Ingredient (API). This article aims to guide procurement managers and R&D scientists in identifying reliable manufacturers and understanding the specifications that matter when looking to buy this chemical.

Gefitinib, a tyrosine kinase inhibitor used primarily for the treatment of non-small cell lung cancer, relies on a precise chemical synthesis pathway. At the heart of this pathway is the intermediate 6,7-Dimethoxyquinazoline-4-one. Its purity directly impacts the yield and quality of the Gefitinib API. Therefore, when seeking to purchase this material, meticulous attention must be paid to its specifications. A high purity level, typically ≥98%, is non-negotiable. Furthermore, a low moisture content, ideally ≤1%, is crucial for maintaining stability during storage and processing, preventing unwanted side reactions, and ensuring consistent reaction kinetics. The physical form, commonly a white crystalline powder, also plays a role in ease of handling and dissolution in various reaction media.

For companies operating in the pharmaceutical sector, establishing a dependable supply chain is as important as the quality of the intermediate itself. Identifying a reputable supplier or manufacturer in China that specializes in pharmaceutical intermediates can provide a significant competitive advantage. Such partners offer not only high-quality products but also the assurance of consistent availability and competitive pricing. By partnering with a dedicated chemical manufacturer, you can mitigate supply chain risks and focus on your core competency: drug development and production. When comparing options, consider manufacturers who provide detailed Certificates of Analysis (CoA) with each batch, outlining the precise purity, impurity profiles, and physical properties.

When you are ready to buy 6,7-dimethoxyquinazoline-4-one for gefitinib synthesis, it is advisable to engage with manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. They understand the stringent demands of the pharmaceutical industry and are equipped to meet them.
