Quality Control

Our production of this advanced intermediate adheres to strict in-process controls to ensure batch-to-batch consistency and high purity. Every lot is characterized using advanced analytical techniques including HPLC, NMR, and GC-MS to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We support cGMP compliance for applications requiring the highest quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from incompatible materials.
