In the rigorous landscape of pharmaceutical manufacturing, precision extends beyond synthesizing the active pharmaceutical ingredient (API). The identification, quantification, and control of impurities are equally critical for drug safety, efficacy, and regulatory approval. 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) exemplifies this principle, serving not only as a vital intermediate in Apixaban synthesis but also as a crucial impurity reference standard. Understanding its role in quality control is essential for any stakeholder in the Apixaban value chain.

Apixaban, a potent oral anticoagulant, undergoes a complex multi-step synthesis. During this process, various by-products and related substances can arise, which are classified as impurities. Ethyl 6-(4-aminophenyl)-1-(4-methoxyphenyl)-7-oxo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxylate is one such compound that may be present. Regulatory bodies worldwide mandate strict limits on the levels of impurities in pharmaceutical products. Therefore, analytical chemists require a well-characterized reference standard of this compound to accurately detect and quantify its presence in Apixaban batches. NINGBO INNO PHARMCHEM CO.,LTD. provides this high-purity standard to support these critical quality assurance efforts.
