In the intricate process of pharmaceutical synthesis, understanding the role of impurities and intermediates is just as crucial as comprehending the final API. 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, identified by CAS 503614-91-3, is a prime example of such a compound. Often referred to as an Apixaban Ethyl Ester Impurity, this chemical is not merely a byproduct but a vital component that requires careful consideration by pharmaceutical researchers and procurement specialists. This article explores its significance and provides insights for those looking to purchase it.

The Dual Role: Intermediate and Reference Standard

The compound with CAS 503614-91-3 serves a dual purpose in the pharmaceutical industry. Firstly, it acts as a key intermediate in the synthesis of Apixaban, a widely prescribed anticoagulant. Its specific chemical structure allows for precise chemical transformations, leading to the formation of the target API. For synthesis chemists, having a reliable source for this intermediate is critical to ensure consistent yields and purity of the final drug product. We understand the demand for this compound and offer it from reputable manufacturers.

Secondly, as its common name suggests, it functions as an important reference standard. In pharmaceutical quality control, reference standards are used to identify and quantify impurities in a drug substance or product. Having a well-characterized standard like the ethyl ester derivative helps analytical laboratories validate their testing methods and ensure that the Apixaban manufactured meets stringent regulatory requirements set by bodies like the FDA. This makes sourcing high-quality material essential for any pharmaceutical quality assurance department.

Technical Specifications and Sourcing Considerations

When seeking to buy CAS 503614-91-3, attention to its technical specifications is paramount. Key details include its molecular formula (C27H28N4O5) and molecular weight (488.54). While various suppliers may offer this compound, it is imperative to verify its purity and physical form. Typically appearing as a white to pale beige solid, its exact specifications are critical for its intended use. For those looking to purchase in bulk, engaging with a trusted supplier that can guarantee consistent quality and provide comprehensive documentation such as a Certificate of Analysis (CoA) is crucial.

For companies based in regions like the USA, or anywhere globally, seeking to procure this pharmaceutical intermediate, understanding the landscape of international sourcing is key. Engaging with suppliers who offer transparent pricing and reliable shipping is also a significant factor. Direct inquiries to manufacturers or specialized chemical distributors can often lead to better understanding of lead times and fulfillment capabilities, especially for research quantities or larger production orders.

In summary, Apixaban Ethyl Ester Impurity (CAS 503614-91-3) is a compound of significant importance in pharmaceutical synthesis and quality control. Whether you are a researcher needing a reference standard or a manufacturer requiring a key intermediate for API production, understanding its properties and sourcing it from reliable providers is vital for successful outcomes.
