Quality Control

Every batch of 1,3-Benzoxaphosphole, 3-(1,1-Dimethylethyl)-4-(2,6-Diphenoxyphenyl)-2,3-Dihydro-, (3S)- is produced and analyzed under strict quality management protocols. We ensure high chiral purity and chemical integrity through advanced analytical techniques including chiral HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with each shipment 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 controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This compound is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air or moisture must be avoided to maintain stability and purity.
