As an accredited 2-Naphthol factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | 2-Naphthol is packaged in a 500g amber glass bottle with hazard labeling, tamper-evident seal, and a screw cap for safety. |
| Shipping | 2-Naphthol is shipped in tightly sealed containers, protected from light, moisture, and incompatible substances. It is classified as a hazardous material and must comply with transport regulations. Proper labeling, handling with personal protective equipment, and storage in a cool, well-ventilated area are required to ensure safe transportation. |
| Storage | 2-Naphthol should be stored in a cool, dry, well-ventilated area away from incompatible substances, such as strong oxidizers, acids, and bases. Keep the container tightly closed and protected from direct sunlight and moisture. Use containers made of materials compatible with organic chemicals. Clearly label storage containers, and ensure access is limited to trained personnel using appropriate safety measures. |
