Quality Control

Our 390 Msd is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled 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.
