Join us for our upcoming live webinar on Tuesday, September 22, 2026, where Nils Schomann, QC Manager Method Development, will explore the analytical challenges of characterizing complex diastereomer mixtures in oligonucleotide therapeutics.
Phosphorothioate linkages are widely used in oligonucleotide therapeutics, but the resulting diastereomeric complexity presents important analytical and manufacturing considerations. This webinar explains why diastereomer distributions matter and introduces analytical approaches for their characterization, including HPLC fingerprinting, ³¹P NMR, and shortmer studies. Attendees will gain deeper insight into fingerprint methods and their application to the characterization and comparison of complex diastereomer mixtures.
