Tri(2-furyl)phosphine CAS 5518-52-5

1. Tri(2-furyl)phosphine is primarily used as a ligand in transition metal catalysis, particularly in cross-coupling reactions (e.g., Suzuki, Heck) and hydrogenation, where the electron-rich furan rings enhance ligand stability and catalytic activity.
2. Tri(2-furyl)phosphine CAS 5518-52-5 serves as a precursor for phosphonium salts, ionic liquids, and bio-based polymers in sustainable material science.
3. Tri(2-furyl)phosphine functions as a building block for heterocyclic compounds and as a reagent in organic synthesis for phosphorus-containing molecules.

1. Store tri(2-furyl)phosphine in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, inert containers under an argon or nitrogen atmosphere to prevent oxidation.
2. Keep tri(2-furyl)phosphine CAS 5518-52-5 strictly separate from strong oxidizing agents, strong acids, and reactive chemicals to avoid hazardous reactions or decomposition.
3. Handle tri(2-furyl)phosphine with care using non-sparking tools and grounded equipment; ensure containers are clearly labeled and stored in a dedicated, secure area.

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid direct contact and prevent the material from entering drains or soil.
2. Carefully collect spilled tri(2-furyl)phosphine CAS 5518-52-5 using a clean, dry tool or a HEPA-filter vacuum cleaner, and place it into a sealed, labeled container for disposal as hazardous chemical waste.
3. Clean the contaminated surface thoroughly with a suitable solvent or detergent under controlled conditions; collect all contaminated materials and dispose of them in full compliance with local, national, and international regulations for phosphorus- and heterocyclic-containing hazardous waste.

1. Tri(2-furyl)phosphine is harmful if swallowed, inhaled, or absorbed through the skin, and may cause skin irritation, serious eye damage, and respiratory tract irritation.
2. Tri(2-furyl)phosphine CAS 5518-52-5 may release toxic phosphorus or furan derivatives upon heating or combustion; prolonged or repeated exposure may affect specific organs.
3. Always handle tri(2-furyl)phosphine in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
