Quality Control

Our 4-Ethoxy-3,5-Difluorobenzoicacid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure compliance with exacting customer specifications and industry best practices. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials such as strong bases and fluorides. The container must be kept tightly sealed due to potential moisture sensitivity.
