alogliptin and its Impurities
Alogliptin is prepared as a benzoate salt. It is a selective, orally-bioavailable inhibitor of enzymatic activity of dipeptidyl peptidase-4, inhibitor that decreases blood sugar similar to the other. Reference standards of Alogliptin API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
