Paper Title
An Investigation into the Formation of Impurity During the Process Development of Sumatriptan Succinate
Abstract
During the process development of sumatriptan succinate, we have observed the formation of unknown impurity
at enhanced level which was identified as a cyclized impurity 7. Present article discussed about the development of robust
process for the commercial production of sumatriptan succinate substantially free from impurities. Identification, isolation
and characterizations of impurity were also discussed.
Keywords: Sumatriptan Impurity, Cyclized Impurity, Indole.
