For procurement managers and R&D scientists in the pharmaceutical sector, sourcing high-quality intermediates is paramount to successful drug development and manufacturing. One such critical compound is 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one (CAS: 13794-72-4), a key intermediate in the synthesis of the targeted cancer therapy, Gefitinib. Understanding how to effectively buy this chemical and identify trustworthy manufacturers is essential.

When looking to purchase 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one, several factors should be considered. Firstly, purity is non-negotiable. A minimum purity of >98% HPLC is typically required for pharmaceutical applications. This ensures that downstream synthesis is efficient and that the final API meets rigorous quality standards. Always inquire about the Certificate of Analysis (COA) provided by the supplier to verify the compound's specifications.

Secondly, consider the reliability of the supplier. A reputable manufacturer will have a consistent production capacity and a robust quality control system. Identifying manufacturers in China that specialize in fine chemical intermediates can offer cost advantages without compromising on quality. Look for suppliers who clearly state their manufacturing capabilities and commitment to regulatory compliance.

The application of 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one extends beyond just being a Gefitinib precursor. It also serves as a valuable research chemical and can be used as a reference standard for Gefitinib impurity analysis. This dual utility underscores the importance of securing a consistent supply from a dependable source.

When seeking a quote for 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one, clearly outline your required quantity, purity specifications, and desired delivery timeline. Engage with potential suppliers, ask detailed questions about their manufacturing processes, and evaluate their responsiveness. For many global pharmaceutical companies, establishing long-term relationships with trusted chemical manufacturers in China is a strategic move to ensure supply chain security and competitive pricing for essential building blocks like this quinazoline derivative.

By focusing on purity, supplier reputation, and understanding the compound's applications, procurement professionals can confidently buy 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one, ensuring their pharmaceutical development projects proceed smoothly and efficiently.
