Quality Control

Our 2-Methoxy-4-Bromo-5-Methylphenol is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity assessment and NMR/IR for structural confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for all commercial quantities. We support custom purity requirements for specific R&D or production needs.

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 to be easily oxidized, prolonged exposure to light and air should be avoided. For long-term storage, consider an inert atmosphere.
