Quality Control

Our cis-Decahydronaphthalene is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. Certificates of Analysis (COA) detailing all quality parameters are provided with every shipment. We adhere to relevant industry standards and can support requirements for cGMP, ISO, or other regulatory frameworks as needed.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and minimize evaporation.
