Quality Control

Our Benzoic Acid, 2-((3,5-Dibromo-4-Hydroxyphenyl)(3,5-Dibromo-4-Oxo-2,5-Cyclohexadien-1-Ylidene)Methyl)-, Methyl Ester is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC, NMR, and elemental analysis, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We support compliance with REACH and other global regulatory frameworks as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
