Quality Control

Every batch of 3-Thia-1.6-Hexanedithiol is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including chromatography and spectroscopy, to ensure compliance with high-purity standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
