Quality Control

Our Oroxine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including identification, assay, and impurity profiling, to meet the stringent requirements of pharmaceutical-grade intermediates. A Certificate of Analysis (COA) detailing all test results is provided with every shipment 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 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.
