Product Overview
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH) is a highly reactive reducing agent supplied as a 70 wt% solution in toluene (approximately 3.5M concentration). This complex hydride offers a balanced reactivity profile, making it ideal for selective reductions in organic synthesis where milder conditions are required compared to lithium aluminium hydride (LAH). The AcroSeal® packaging ensures minimal exposure to moisture and air, preserving the reagent’s potency and extending shelf life. The toluene solvent provides excellent solubility for organic substrates while maintaining stability during storage. This solution is particularly valued for its ability to reduce esters, aldehydes, and ketones with controlled selectivity, often leaving other functional groups intact. The reagent’s solubility and reactivity can be further modulated by adjusting reaction conditions, offering versatility in synthetic applications. Proper handling under inert atmosphere is recommended due to its moisture-sensitive nature.
FAQs
1. What is the typical shelf life of this sodium bis(2-methoxyethoxy)aluminium hydride solution?
The solution remains stable for 12-18 months when stored unopened in its original AcroSeal® packaging at recommended temperatures.
2. Can this reagent be used as a direct substitute for lithium aluminium hydride?
While it serves similar purposes, SMEAH generally offers milder reducing conditions and better selectivity for certain functional groups compared to LAH.
3. What precautions should be taken when handling this toluene solution?
Always work in a well-ventilated fume hood, use moisture-free glassware, and maintain an inert atmosphere to prevent decomposition.
4. Is this solution compatible with common organic solvents?
The toluene-based solution mixes well with most aprotic organic solvents but may react violently with protic solvents like alcohols.
5. How should I dispose of excess solution after use?
Neutralize carefully with isopropanol or ethanol under controlled conditions before disposal according to local hazardous waste regulations.
