In the complex world of pharmaceutical manufacturing, the reliable sourcing of high-quality intermediates is paramount. For the production of Apixaban, a critical oral anticoagulant, ethyl 6-(4-aminophenyl)-1-(4-methoxyphenyl)-7-oxo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylate (CAS: 503615-07-4) stands out as a key building block. Understanding its role and how to procure it effectively can significantly impact the efficiency and cost-effectiveness of your Apixaban API synthesis.

Apixaban's efficacy as a direct factor Xa inhibitor relies heavily on the purity and structural integrity of its precursor molecules. Ethyl 6-(4-aminophenyl)-1-(4-methoxyphenyl)-7-oxo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylate, often referred to by its CAS number 503615-07-4, plays a crucial role in the multi-step synthesis of this vital drug. Its precise chemical structure and high purity are essential to ensure the final API meets stringent pharmacopoeial standards. Therefore, when seeking to buy this intermediate, prioritizing quality and reliability is non-negotiable.

For many pharmaceutical companies, the question of where to purchase such specialized chemicals is critical. Manufacturers based in China have emerged as significant global suppliers, offering competitive prices due to economies of scale and advanced manufacturing capabilities. When searching for a reliable supplier of ethyl 6-(4-aminophenyl)-1-(4-methoxyphenyl)-7-oxo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylate, it is vital to vet potential partners based on their quality control systems, production capacity, and adherence to international standards. Look for suppliers who can provide detailed Certificates of Analysis (CoA) and demonstrate a strong understanding of pharmaceutical intermediate requirements.

The price of pharmaceutical intermediates can vary, influenced by factors such as purity, order volume, and the supplier's overheads. However, by establishing direct relationships with manufacturers, pharmaceutical companies can often secure more favorable pricing for bulk purchases. This direct procurement model not only benefits the bottom line but also fosters a more transparent and stable supply chain. Exploring options for purchasing CAS 503615-07-4 from China can unlock significant cost savings without compromising on the quality needed for sensitive pharmaceutical applications.

In conclusion, if your company is involved in the production of Apixaban or requires high-purity heterocyclic intermediates, focusing on ethyl 6-(4-aminophenyl)-1-(4-methoxyphenyl)-7-oxo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylate is key. By partnering with experienced manufacturers and suppliers who prioritize quality and offer competitive pricing, you can ensure a consistent and dependable supply of this critical component, ultimately contributing to the successful development and availability of life-saving medications. Investigate reputable Chinese manufacturers for your next purchase of this essential pharmaceutical intermediate.
