Quality Control

Every batch of our chiral specialty chemicals is produced and verified under stringent quality protocols. We guarantee high chemical and chiral purity through comprehensive analytical techniques including HPLC, NMR, and chiral analysis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting identity, purity, and enantiomeric excess. Our quality management system supports compliance with cGMP and ISO standards for research and development applications.

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 a controlled 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.
