Quality Control

Our (Biphenyl-4-Yloxy)Acetyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical specifications. Our quality commitment ensures the material meets the stringent requirements for research and cGMP-grade intermediate synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and oxidizing agents.
