As an accredited (S)-(-)-DM-SEGPHOS® factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The 1-gram (S)-(-)-DM-SEGPHOS® comes in a tightly sealed amber glass vial with tamper-evident cap and detailed labeling. |
| Shipping | (S)-(-)-DM-SEGPHOS® (Sigma Aldrich/Merck/TCI Chemical Grade) is typically shipped in sealed glass or inert plastic containers, protected from air and moisture. Packaging adheres to international regulations for hazardous materials. During transit, it is kept under dry, temperature-controlled conditions, often with desiccants, to maintain chemical integrity and ensure safe delivery. |
| Storage | (S)-(-)-DM-SEGPHOS® should be stored under an inert atmosphere (such as nitrogen or argon) in a tightly sealed container. Keep it in a cool, dry place, preferably at 2–8°C (refrigerated). Protect from moisture, heat, and direct sunlight. Avoid exposure to air, as the phosphine ligand is air-sensitive and can degrade or oxidize upon contact with oxygen or water. |
