Quality Control

Our 1,2,3,4,4A,5,6,8A-Octahydro-4A,8-Dimethylnaphthalene is manufactured under strict quality management systems. Each batch is analyzed to ensure it meets stringent purity and identity specifications, supported by a comprehensive Certificate of Analysis (COA). We are committed to providing reliable, consistent quality for your critical applications, with specifications tailored to R&D, pilot, and commercial-scale requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert atmosphere to maintain optimal purity.
