A novel stability-indicating UHPLC method for the determination of related substances and assay in a synthetic opioid peptide Difelikefalin acetate and LC–MS identification of the major degradation products
Key Points
Difelikefalin acetate shows consistent stability when assessed with a novel UHPLC method—confirming its suitability for detailed analysis.
The assessment identifies degradation products effectively, demonstrating a significant metric of stability and reliability in analysis.
Employing UHPLC coupled with LC-MS techniques, the method reveals major degradation products efficiently under controlled conditions.
Results support the ongoing use of Difelikefalin in clinical settings, calling for confidence in its stability and effectiveness against degradation.
