Description
Des-Lys17-Retatrutide (incl. Side Chain) 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 lacks part or all of the fatty-acid side chain normally attached to Retatrutide (here: Des-Lys17 (Side Chain)), resulting from incomplete side-chain conjugation or side-chain cleavage. Side-chain–truncated variants are key process-related impurities for acylated GLP-1 receptor agonists. It can serve as a qualitative marker for retention-time and mass confirmation when profiling Retatrutide samples by HPLC and LC-MS.
