Quality Control

Our (R)-Vapol is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency. Each lot is characterized by advanced analytical techniques, including HPLC, NMR, and chiral analysis. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and other critical parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at room temperature (15-25°C). This compound is easily oxidized and light-sensitive; prolonged exposure to air or light should be avoided to maintain stability and purity.
