Quality Control

Our Tris[2-Mercaptoethyl] Orthoborate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including purity assay and identification, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee traceability and consistency.

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 the presence of thiol groups, the material should be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent oxidation. Keep away from strong oxidizing agents.
