Quality Control

Our 1,12-Dodecanediyl-Bis(Tributylphosphonium) Dibromide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
