Quality Control

Our production of this high-purity intermediate adheres to stringent ISO 9001 quality management standards. Every batch undergoes comprehensive analytical characterization using HPLC, GC, NMR (1H, 19F, 13C), and Mass Spectrometry to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical specifications such as assay purity and impurity profiles to ensure batch-to-batch consistency and reliability for your research and development processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. For long-term storage, consider storing under an inert atmosphere to maintain optimal stability.
