Sodium bis(2-methoxyethoxy)aluminumhydride (trade names Red-Al, Synhydrid, Vitride) is an organoaluminium compound with the formula NaAlH₂(OCH₂CH₂OCH₃)₂. The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis. The compound features a tetrahedral aluminium center attached to two hydride and two alkoxide groups, the latter derived from 2-methoxyethanol. Commercial solutions are colourless/pale yellow and viscous. At low temperatures, the solution solidifies to a glassy pulverizable substance. No sharp melting point was found.
