Quality Control

Our n-Butylphthalide-037 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure it meets high-purity standards suitable for pharmaceutical intermediate use. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 properties of being light-sensitive and easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame.
