Quality Control

Our Picrasin-E is produced and tested under strict quality management protocols to ensure high purity and batch-to-batch consistency, suitable for research and development purposes. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We support compliance with relevant standards for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This product is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric moisture.
