Quality Control

Every batch of Fmoc-Asu-Oh is manufactured under strict quality management systems. Our products undergo rigorous quality testing, including HPLC for purity and identity confirmation, to ensure compliance with industry standards for peptide synthesis. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to maintain stability and purity. For long-term storage, consider desiccation.
