CAS :<p>(R)-Sitagliptin rac-fumarate adduct is an analytical reference material and impurity standard. It is a natural product that is synthesized using a custom synthesis with analytical data available. The impurities of the synthetic process are well defined, with the exception of (1) an unknown peak at retention time 9.7 min and (2) a peak at retention time 12.5 min that may be due to the presence of fumaric acid or its derivatives. This product can be used for drug development research and development, as well as for establishing HPLC standards for pharmacopoeia testing.</p>Formule :C20H19F6N5O5Degré de pureté :Min. 95%Masse moléculaire :523.40 g/mol
