Quality Control

Our Ethyl Bis(3,5-Dibromo-4-Hydroxyphenyl)Acetate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and bromine content. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed when not in use to prevent degradation from moisture absorption and light exposure.
