Description

D-Tyr1-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. In this variant, the L-tyrosine at position 1 is replaced by its D-enantiomer, a racemization-related impurity that can arise during solid-phase peptide synthesis or under stress conditions. It can serve as a qualitative marker for retention-time and mass confirmation when profiling Retatrutide samples by HPLC and LC-MS.
