Quality Control

Our 1,1-Spirobi(1H-Indene)-4,4,5,5,6,6-Hexol,2,2,3,3-Tetrahydro-3,3,3,3-Tetramethyl is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, NMR for structural confirmation, and loss on drying tests. A detailed Certificate of Analysis (COA) documenting all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect purity and stability. For long-term storage, consider the use of desiccants.
