Quality Control

Our n-Biotinyl p-Aminophenyl Arsinic Acid is produced under strict quality management protocols to ensure high purity and batch-to-batch consistency, suitable for research and development applications. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We adhere to relevant quality guidelines to support our global clientele in pharmaceutical and life science industries.

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 desiccated environment to prevent degradation. For long-term storage, consider inert atmosphere conditions.
