[α-Glu]-Retatrutide (Side Chain) Impurity

Descriptionα-Glu-Retatrutide (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 involves an isomeric variation in the glutamic acid linker of the Retatrutide side chain (e.g., α- vs γ-linkage or D-configuration), which can arise from raw-material impurities or side reactions during side-chain conjugation. It can serve as a qualitative marker for retention-time and mass confirmation when profiling Retatrutide samples by HPLC and LC-MS.Specifications Parameter Value Product Category Retatrutide Impurity Grade Research grade (for analytical use only) Appearance Off-white lyophilized powder Catalog Number BF-RTR-alpha-Glu Package Size 50 mg (custom sizes available upon request) Purity ≥95% (HPLC) Salt Form Sodium salt CAS Number N/A Parent Compound CAS 2381089-83-2 (Retatrutide) Molecular Formula C221H342N46O68 Molecular Weight 4731.42 Solubility 20% ACN in water Storage Condition -20±5°C, protect from light and moisture Synonyms [α-Glu](Side Chain)Retatrutide; Side-chain linker isomer impurity Applications Impurity identification and peak tracking in HPLC and LC-MS analysis Analytical method development and optimization Process-related impurity research for Retatrutide peptide synthesis Forced degradation and stability research Retention-time and mass confirmation as a qualitative marker Custom sizes and specifications are available upon request.
