Quality Control

Our high-purity batch of this advanced intermediate is produced under strict quality management systems. Each lot undergoes comprehensive analytical characterization, including HPLC for purity assessment, NMR (1H & 13C) for structural confirmation, and mass spectrometry for identity verification. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to ensure full traceability and support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
