Quality Control

Our 3-tert-Butyl-5-Bromophenol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring GMP-grade intermediates and research chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents, strong acids, and strong bases.
