| Shipping | JohnPhos (chemical name: 2-(Di-tert-butylphosphino)biphenyl) is shipped by Sigma-Aldrich, Merck, or TCI in sealed, inert atmosphere containers to prevent oxidation and moisture exposure. It is classified as a hazardous material; shipping complies with international and local regulations for chemicals, often requiring temperature control and specialized packaging. |
| Storage | JohnPhos should be stored in a tightly sealed container under an inert atmosphere (such as nitrogen or argon) to prevent degradation. It should be kept in a cool, dry place, away from heat, moisture, and sources of ignition. Storage under refrigeration (2–8°C) is recommended. Avoid exposure to air and light, as the compound is sensitive to both. |
