Quality Control

Our production of this high-value intermediate adheres to strict quality management systems. Each batch is characterized and tested to ensure identity, purity, and consistency, supporting your critical R&D and scale-up activities. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC), identity confirmation (e.g., NMR, IR), and impurity profiles is provided with every shipment.

Storage

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