Quality Control

Our high-purity organogold complexes are manufactured under controlled conditions to ensure batch-to-batch consistency and reliability. Each lot undergoes rigorous analytical testing, including NMR (1H, 13C), HPLC, and elemental analysis, to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon or nitrogen) at 2-8°C to maintain stability. This material is moisture-sensitive and easily oxidized; ensure containers are sealed immediately after use and stored in a cool, dry, and well-ventilated area.
