Quality Control

Our Dihydralazine Sulphate is manufactured and tested to meet stringent pharmaceutical-grade standards. Each batch undergoes comprehensive analysis including identification, assay, and impurity profiling to ensure compliance with relevant pharmacopoeial guidelines. Certificates of Analysis (COA) documenting purity, related substances, and residual solvents are available upon request to support your regulatory filings.

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 in a low-humidity environment to prevent degradation.
