Quality Control

Our [1R,4R,(+)]-2,2-Dimethyl-5-Methylenebicyclo[2.2.1]Heptane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical and chiral purity, meeting the stringent requirements for research and process chemistry. Certificates of Analysis (COA) with detailed chromatographic data (GC, HPLC) and optical rotation values are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flame.
