Macitentan ACT-373898
Macitentan ACT-373898 is a brominated pyrimidinone derivative featuring a sulfonamide linkage and a substituted pyrrolidinyl pentyl chain, structurally analogous to Macitentan but with a 4-bromoanilino substitution in place of the methoxyphenyl group. This impurity arises from a divergent pathway during sulfonamide coupling, introducing a bromine atom at the aniline moiety. It serves as an HPLC reference standard for quantifying this specific process-related impurity in Macitentan active pharmaceutical ingredient synthesis.
