Quality Control

Our production of this high-purity specialty chemical adheres to strict quality management protocols. Every batch is characterized using advanced analytical techniques including NMR, HPLC, and chiral analysis to confirm identity, purity, and enantiomeric excess. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
