Description

Trazodone BP Impurity E, also designated Trazodone 4-Ethyl Impurity, corresponds to a structurally related process-related impurity of trazodone, CAS 1346599-35-6. With molecular formula C21H26ClN5O and molecular weight 399.92 g/mol, it retains the triazolopyridinyl and chlorophenyl motifs characteristic of the parent scaffold while bearing an ethyl-substituted side-chain variant. Such impurities are typically associated with incomplete alkylation, side-chain rearrangement, or minor synthetic route deviations. Characterization generally requires LC-MS/MS for selective detection and structural assignment, with complementary HPLC-UV and, where necessary, high-resolution MS to support impurity profiling under pharmacopeial and ICH Q3A/Q3B expectations.
