Quality Control

Our Hydrindantin Dihydrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high performance in sensitive analytical applications. Each lot undergoes comprehensive testing, including identity confirmation, purity assay, and verification of suitability for use in ninhydrin reagent formulations. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

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 light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers to prevent degradation.
