Quality Control

Our Phenylalanyl-3-Thiaphenylalanine is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analytical characterization, including HPLC for purity, MS for identity confirmation, and chiral analysis. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment 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 (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or an inert atmosphere.
