Description

Endo-Ser32-Retatrutide Impurity is a high-purity peptide impurity of Retatrutide, supplied as a research-grade analytical material for impurity identification, analytical method development and quality-control research. This insertion impurity contains an additional serine at position 32 (duplicated residue) in the Retatrutide sequence, typically resulting from double coupling during solid-phase peptide synthesis. It can serve as a qualitative marker for retention-time and mass confirmation when profiling Retatrutide samples by HPLC and LC-MS.
