Quality Control

Our 2,6-Di-tert-Butyl-4-Methylene-2,5-Cyclohexadienone is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to light and tendency for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
