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) is a primary aromatic amine-bearing tetrahydropyrazolopyridine ester. It is also known as Apixaban Amino Intermediate. This intermediate is likely to be a process-related impurity. If this intermediate impurity is present in amounts greater than 0.10%, as per ICH Q3A it must be identified and qualified.
ApiSyn provides this Apixaban synthesis intermediate (CAS 503615-07-4) as an intermediate and Apixaban API quality assurance application.
