Quality Control

Our 1,2-Epoxycyclododecane is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to verify identity and assay. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage.
