Quality Control

Our (11Ar)-(+)-10,11,12,13-Tetrahydrodiindeno[7,1-De:1',7'-Fg][1,3,2]Dioxaphosphocin-5-Phenoxy is produced under strict quality management protocols to ensure batch-to-batch consistency and high chiral purity. Each lot undergoes rigorous analytical testing, including chiral HPLC and NMR, to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance in regulated research environments.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
