Quality Control

Our (R)-Boroser(Obn)-(+)-Pinanediol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC and structural confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) when opening to prevent degradation. Keep the container tightly sealed when not in use.
