Quality Control

Our 1-Phenyl-2,4-cyclohexadiene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and structural confirmation, to ensure it meets the high standards required for research and synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay purity and identity. We support custom synthesis and can tailor specifications to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Recommended storage temperature is between 2°C and 8°C (refrigerated) for long-term stability, as the conjugated diene system may be susceptible to oxidation and polymerization over time. Allow the container to reach ambient temperature before opening to prevent moisture condensation. Keep away from heat, sparks, and open flames.
