Quality Control

Our Methylcyclopentadiene is produced 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. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Due to its highly volatile nature, containers must be kept tightly sealed when not in use. Recommended storage temperature is 2-8°C (36-46°F) to minimize dimerization and polymerization. Keep away from strong oxidizing agents.
