Quality Control

Our Diphenylselenium Dibromide is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and purity.
