Quality Control

Our Deamino-Tyr-Tyr Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or cGMP guidelines for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere (e.g., nitrogen or argon) after each use to prevent degradation. Keep away from strong oxidizing agents.
