Quality Control

Our 2-(4-Aminophenoxy)Acetic Acid Hydrate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) that include results for assay, related substances, residual solvents, and other critical parameters. Our quality commitment ensures the material is suitable for demanding applications in pharmaceutical and fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat and incompatible materials.
