Quality Control

Our Ethyl 3-Acetoxy-4-Hydroxybenzoate is produced 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, GC, and other relevant analytical methods. Specifications can be tailored to meet cGMP or other specific regulatory requirements for pharmaceutical or agrochemical applications.

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 nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents, strong bases, and strong acids.
