Description
Semaglutide Endo-Ser11 impurity is a high-purity impurity reference standard designed for pharmaceutical quality control, analytical method development, and regulatory compliance testing of Semaglutide. This insertion impurity contains an additional serine at position 11 (duplicated residue) in the Semaglutide sequence, typically resulting from double coupling during solid-phase peptide synthesis. This reference material supports accurate impurity identification, structural confirmation, and quantitative analysis by HPLC and LC-MS in peptide drug development and manufacturing workflows.
