Description
Ser39-OH-Retatrutide (C-Terminal Acid) 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 impurity carries a free C-terminal carboxylic acid (Ser39-OH) instead of the native C-terminal amide, resulting from C-terminal deamidation or incomplete amidation. It can serve as a qualitative marker for retention-time and mass confirmation when profiling Retatrutide samples by HPLC and LC-MS.
