Quality Control

Our cis-1,3-Dimethyl-2-Methylenecyclohexane is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to verify identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP principles where applicable to support our clients in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, containers should be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) when not in use to prevent degradation and maintain purity. Recommended storage temperature is 2-8°C for long-term stability.
