Quality Control

Our n-(2-Hydroxyethyl)Amidophosphoric Acid Bis(2,3-Dibromopropyl) Ester is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, bromine content, and thermal stability critical for flame retardant performance. Certificates of Analysis (COA) detailing assay, impurity profile, and physical properties are available upon request.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, containers should be kept in opaque packaging or dark storage conditions.
