Quality Control

Our 3,4-Epoxycyclohexylmethyl 3,4-Epoxycyclohexane Carboxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, epoxide content, and impurity profiling, to ensure it meets precise specifications for high-performance applications. Certificates of Analysis (COA) documenting purity, viscosity, color, and other critical parameters are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve epoxide functionality and prevent viscosity increase.
