Quality Control

Every batch of Altertoxin Ii is produced and analyzed under strict quality management protocols to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay purity and impurity profiles. Our quality systems are designed to meet the exacting requirements of research and analytical applications, ensuring reliable and reproducible results for our clients.

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 tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
