Quality Control

Our 3-n-Butylphthalide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring GMP-grade or high-purity research materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
