Quality Control

Every batch of 4-Amino-3-Ethoxybenzoic Acid is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure compliance with high-purity standards suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and quality assurance for your projects.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
