Quality Control

Our n-(4-Hydroxyphenyl)-2-Naphthylamine is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, to meet the specified 97% minimum purity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with our rigorous internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive (store away from light), it is recommended to handle under an inert atmosphere for long-term storage and minimize exposure to air and light during use.
