Quality Control

Our 1,2,4,5-Benzenetetrathiol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

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 and light, minimize exposure to air and direct light during handling.
