Quality Control

Our Tyrosyl-Alanylglycyl-Phenylalanyl-Cysteine S-Butyl Ester is manufactured under controlled conditions to ensure high purity and batch-to-batch consistency. Quality is verified through a comprehensive suite of analytical techniques including HPLC, MS, and NMR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each batch to support your research and regulatory 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 (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
