Quality Control

Our Allomethadione is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling via modern techniques like HPLC and GC. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with customer specifications and relevant industry guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which could affect product stability and performance.
