Quality Control

Our 4-Bromo-3,5-Dimethylphenol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with global regulatory frameworks, including REACH.

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). 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 flame.
