Author(s): Maruthi Raju N, Venkateswara Rao B, Siddaiah V

Fingolimod (1) is an immunomodulating drug, frequently used for treating Multiple Sclerosis (MS) approved by the US-FDA. During the process development of Fingolimod, some process related impurities were observed along with the final API. These impurities were identified as N,N-dimethyl (2), N-methyl (3), nitromono methyl (4), monomethyl (5), nitrohydroxy (6) and hydroxy (7) impurities. The present work describes the synthesis and characterization of these impurities.
