Quality Control

Our 4-n-Pentyloxybenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, NMR, and IR spectroscopy to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment, confirming compliance with customer specifications and industry standards.

Storage

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