Quality Control

Our Butyloxycarbonyl-Tryptophyl-Leucyl-Aspartyl-Phenylalaninamide is manufactured under strict quality systems to ensure batch-to-batch consistency and high purity for research applications. We provide comprehensive analytical data, including HPLC purity, chiral purity, and identity confirmation. Certificates of Analysis (COA) detailing all specifications and test results are available for every batch upon request.

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 tightly sealed in a dry environment to prevent moisture absorption, which can affect stability. For long-term storage, consider desiccated conditions.
