Quality Control

Our 1,1-Biphenyl-2,2-Dithiol, 3,3-Dimethyl- is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a Certificate of Analysis (COA) with key parameters including assay (by HPLC), identification (IR), and impurity profile. Our quality systems are designed to support research and development as well as scale-up manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
