Quality Control

Our 3-Dimethylaminophenol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling via modern techniques like HPLC and GC. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, ensuring the material meets your precise technical requirements and internal specifications.

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 (store under inert atmosphere), it is recommended to keep the container sealed under an inert gas blanket after opening for extended storage.
