Quality Control

Our 4-Amino-3-Ethylbenzoic Acid is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthesis and research applications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
