Sodium diethyldihydroaluminate
CAS: 17836-88-3
Category: Inorganic Chemicals
| Purity | Solution grade: typically 25 wt% sodium diethyldihydroaluminate in toluene with about 5% THF, with a |
| Molecular Formula | C4H12AlNa |
| Molecular Weight | 110.11 |
| Appearance | White crystalline solid; typically supplied as a colorless to slightly yellow solution (about 25 wt%) in toluene under inert gas |
| Packaging | Poly-coated Sure/Seal™ bottles or similar sealed reagent bottles (e.g., 25–100 mL) containing 25 wt% solution in toluene, packaged under nitrogen; larger metal cans or drums under inert atmosphere for bulk supply |
| Testing Indicators | Appearance — visual inspection of solution (color and clarity); Active hydride content (assay) — volumetric titration based on controlled hydrolysis and back-titration; Density — hydrometer or digital density meter; Moisture — Karl Fischer titration; Identification — FTIR (Al–H and C–H bands) and, where applicable, NMR; Residual solvent composition (toluene/THF) — GC analysis as required by specification. |
| Storage Notes | Store under inert gas (nitrogen) in tightly closed containers. Keep in a cool, dry, well-ventilated area designated for flammable, moisture-sensitive reagents. Protect from air, moisture, heat, sparks, and open flame. Do not open containers outside an inert atmosphere and avoid contact with water, alcohols, and other protic solvents. |
| Lead Time | 10 days |
Strong metal hydride reducing agent used in organic synthesis. Employed as a powerful hydride donor, comparable in reducing power to lithium aluminium hydride, for the reduction of carbonyl and other reducible functional groups. Commonly supplied as a 25 wt% solution in toluene (with approximately 5% THF) for use under inert atmosphere conditions.
