Quality Control

Our 1,5-Pentanedithiol is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR), and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated area, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, prolonged exposure to air and elevated temperatures should be avoided. Recommended storage temperature is 2-8°C for long-term stability.
