Quality Control

Our Atl 146E is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. All materials undergo rigorous analytical testing, including chromatographic purity assays and identity confirmation. A Certificate of Analysis (COA) detailing specific test results is provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
