Quality Control

Our Ethyl 3,5-Dihydroxybenzoate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes results from HPLC, IR, and other relevant tests. Our quality commitment ensures the material is suitable for demanding applications in GMP-compatible synthesis and research.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product quality.
