As an accredited Alkyllithium factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | 500 mL amber glass bottle, sealed with a PTFE-lined cap, inside a steel canister, labeled "Alkyllithium", with hazard warnings. |
| Shipping | Alkyllithium compounds must be shipped as dangerous goods, strictly adhering to UN 3394/3399 regulations. They are packed in sealed containers under inert gas, such as nitrogen or argon, and placed in secondary protective packaging. Transport follows strict temperature controls and labeling requirements to prevent hazardous reactions with air, moisture, or incompatible substances. |
| Storage | Alkyllithium compounds must be stored under an inert atmosphere, such as nitrogen or argon, in tightly sealed, moisture-free containers, typically made of glass or stainless steel. These chemicals are highly reactive and pyrophoric, igniting spontaneously in air and reacting violently with water. Storage should be in a cool, dry, well-ventilated area, away from heat, oxidizers, and acids. |
