Quality Control

Our (2S)-2-[[(2S)-6-Amino-2-[[(2S)-1-[(2S)-Pyrrolidine-2-Carbonyl]Pyrrolidine-2-Carbonyl]Amino]Hexanoyl]Amino]-5-(Diaminomethylideneamino)Pentanoic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical research. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
