Quality Control

Our Di-n-Undecyldisulphide is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography and spectroscopic methods, to verify identity and assay. A Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request to support your quality assurance protocols.

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 material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents, heat, and ignition sources.
