Description

Ibuprofen EP Impurity F, CAS 65322-85-2, is a defined organic process-related impurity associated with the ibuprofen impurity profile and characterized by formula C13H18O2 and molecular weight 206.28 g/mol. Structurally, it represents a nonpolar arylalkanoic acid derivative arising from side-chain rearrangement or related synthetic diversification during Friedel Crafts acylation and subsequent reduction sequences. Its monitoring is typically performed by reversed-phase HPLC with UV detection, complemented by LC-MS or GC-MS for trace-level confirmation. The compound is not classified as a nitrosamine or other direct mutagenic structural alert, but its presence is relevant to impurity specification and pharmacopeial identity control.
