Quality Control

Our production of this advanced intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. A Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect reactivity and stability. Keep away from incompatible materials.
