Quality Control

Our Sr 202 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including chromatography and spectroscopy methods, to meet the stringent requirements of our industrial and research partners. A Certificate of Analysis (COA) detailing purity, identity, and key physical parameters is provided with every shipment to guarantee product integrity and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
