Quality Control

Our 4,5-Dihydrotoluene is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including purity assay and impurity profiling, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, away from heat sources and open flame. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable. Keep container tightly sealed when not in use to prevent evaporation and potential contamination.
