Quality Control

Our H-Tyrosyl-Cyclo(Cysteinyl-Phenylalanyl-Penicillaminyl)-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis to ensure stereochemical integrity. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific client or pharmacopeial requirements.

Storage

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