Storage Condition	Store in a cool, dry, well-ventilated area away from incompatible substances such as oxidizing agents, acids, and moisture

Application Areas

Chemical synthesis: Participate in coupling reactions or selective reduction reactions as a Lewis acid.
Electroplating industry: used for the preparation of nickel coatings.
Catalyst: catalyzing the formation of carbon carbon bonds in organic synthesis

Storage conditions

Environmental requirements: Store in a cool, dry and sealed place, avoiding contact with oxides and moisture.
Temperature control: Store at room temperature, powder is easily deliquescent, and should be moisture-proof.
Container selection: Use a sealed container (such as a glass bottle or an inert gas shielded container)

Safety precautions

Operation protection: Wear chemical resistant gloves, goggles, and dust masks to avoid inhaling dust. Do not eat or smoke while operating inside the fume hood.
Toxicity risk: Class 1 carcinogens, long-term exposure may cause sensitization or carcinogenesis. Seek medical attention immediately after ingestion or skin contact.
Leakage treatment: Cover with inert adsorbent material (such as sand) and dispose of as hazardous waste
