Quality Control

Our Alizarin Complexone is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. Each lot undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical 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 tightly sealed after each use to prevent degradation from atmospheric moisture.
