Quality Control

Our 4-Butoxy-3-Methoxybenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the stringent requirements of our global B2B clients. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

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