Quality Control

Our Mopidralazine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediates. Certificates of Analysis (COA) detailing specifications such as assay, related substances, and residual solvents are provided with every shipment to support your regulatory and quality assurance 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.
