Quality Control

Our production of this advanced intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Every lot is analyzed using advanced chromatographic and spectroscopic techniques, including HPLC, GC, and NMR, to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We support development and commercial projects requiring compliance with cGMP and ICH Q7 guidelines.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
