Quality Control

Our 3,3,5-Trimethylcyclohexyl Methacrylate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) and infrared spectroscopy (IR), to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its reactivity with strong acids and organic solvents, ensure proper segregation in storage areas. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
