Quality Control
Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and chiral analysis to confirm identity, purity, and enantiomeric excess. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting your quality assurance and regulatory documentation needs.
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 compound is hygroscopic (moisture-sensitive) and should be handled under dry conditions to prevent degradation. For long-term storage, consider desiccants or an inert atmosphere.
