Quality Control

Every batch of H-Arg-Arg-Ala(2-Naphthyl)-Cys-Tyr-Arg-Lys-D-Lys-Pro-Tyr-Arg-Cit-Cys-Arg-Oh is manufactured under strict quality management systems. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing purity (typically by HPLC), molecular weight confirmation (MS), and other critical parameters are available upon request to support your research and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to minimize condensation and moisture uptake. For long-term storage, consider under an inert atmosphere.
