The journey of a pharmaceutical drug from laboratory discovery to full-scale production relies heavily on the availability of high-quality chemical building blocks. For Apixaban, a potent anticoagulant, the ethyl ester derivative, Ethyl 1-(4-methoxyphenyl)-7-oxo-6-[4-(2-oxopiperidin-1-yl)phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylic acid ethyl ester (CAS 503614-91-3), stands as a critical intermediate. Whether you are an R&D scientist exploring new synthesis routes or a production manager scaling up operations, understanding how to source this compound effectively is vital. This article aims to guide you through the process of acquiring this crucial chemical, emphasizing purity, reliability, and the importance of partnering with reputable suppliers.

The Significance of CAS 503614-91-3 in Apixaban Synthesis

Apixaban is a direct factor Xa inhibitor used to prevent blood clots. The synthesis of such complex molecules involves multiple steps, each requiring precise chemical compounds. CAS 503614-91-3 serves as a pivotal intermediate in this process. Its specific chemical structure allows for further transformations to yield the final API with high efficiency and purity. For R&D scientists, having access to this intermediate in small quantities allows for process optimization and exploration of alternative synthesis pathways. For production teams, securing a consistent supply of this compound is essential for maintaining uninterrupted manufacturing schedules and ensuring the cost-effectiveness of the final product. When you are ready to buy, consider companies that understand these critical stages.

Key Considerations for Sourcing High-Purity Material

When seeking to purchase CAS 503614-91-3, several factors are paramount:

• Purity Levels: For pharmaceutical synthesis, purity is non-negotiable. Look for suppliers who guarantee high purity levels, often exceeding 98%. Detailed Certificates of Analysis (CoAs) that outline analytical methods (HPLC, NMR, MS) and results are indispensable. Understanding impurity profiles is crucial for subsequent steps.
• Physical Properties: The compound is typically a white to pale beige solid. Confirming its physical form and stability is important for handling and storage.
• Supplier Reliability: Partner with established chemical manufacturers and distributors who have a proven track record in supplying pharmaceutical intermediates. Companies offering comprehensive technical support and transparent communication are highly desirable. When searching for a supplier in China, look for those with experience in exporting to your region.
• Scalability: Your needs may evolve from R&D quantities to bulk production. Ensure that your chosen supplier can accommodate your scaling requirements. A responsive manufacturer will be able to adjust their production capacity to meet your demand.

Finding the Right Partner and Pricing

Sourcing this ethyl ester derivative involves more than just finding the lowest price. While competitive pricing is important, especially for large-scale production, it should not compromise quality or reliability. Engage with suppliers to understand their manufacturing capabilities and quality control measures. Requesting quotations (RFQs) from multiple sources will provide a clearer picture of the market price and help in negotiation. Building a strong relationship with a reputable manufacturer ensures not only a stable supply but also potential benefits in terms of technical collaboration and long-term cost advantages.

In conclusion, sourcing high-purity Ethyl 1-(4-methoxyphenyl)-7-oxo-6-[4-(2-oxopiperidin-1-yl)phenyl]-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylic acid ethyl ester (CAS 503614-91-3) for Apixaban synthesis requires a focused approach. By prioritizing purity, verifying supplier reliability, and understanding the scalability of their operations, both R&D scientists and production managers can secure this critical intermediate, paving the way for efficient and successful pharmaceutical development and manufacturing.
