Quality Control

Every batch of (1R,3Ar,7Ar)-1-((2R,5S)-5,6-Dimethylheptan-2-Yl)-7A-Methyloctahydro-1H-Inden-4-Ol is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure identity, purity, and stereochemical integrity, typically including chiral HPLC, NMR, and GC-MS analysis. Certificates of Analysis (COA) are available for all shipments, detailing batch-specific results against agreed specifications.

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 minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
