Quality Control

Our 3-(2-Hydroxy-Ethoxy)-Benzoic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and physical characteristics. Our quality commitment ensures the material meets the high standards required for research and industrial synthesis.

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). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect quality and stability.
