Product Overview
Di-n-butylmagnesium, supplied as a 0.5M solution in heptane under the AcroSeal® packaging system, is a highly reactive organomagnesium compound designed for air-sensitive applications. The solution is stabilized in anhydrous heptane to prevent premature decomposition, ensuring consistent performance in synthetic protocols. This synthesis-grade reagent is particularly valued for its ability to function as a strong base and nucleophile, facilitating carbon-carbon bond formation in organic synthesis. The AcroSeal® packaging provides an inert atmosphere, minimizing exposure to moisture and oxygen during storage and handling. Each batch undergoes rigorous quality control to guarantee the specified molar concentration and purity, eliminating variability in experimental outcomes. The solution’s clear, pale yellow appearance indicates proper formulation, while its solubility in non-polar solvents makes it compatible with standard organic reaction setups. For laboratories requiring reliable organometallic reagents, this product offers a balance of reactivity, stability, and ease of use, with the added assurance of sealed packaging to maintain integrity until use.
FAQs
1. What is the shelf life of Di-n-butylmagnesium 0.5M in heptane when stored properly?
The solution remains stable for 12 months from the date of manufacture when stored unopened in its original AcroSeal® packaging at temperatures between 2°C and 8°C. Avoid prolonged exposure to light or heat.
2. Can this reagent be used as a direct substitute for n-butyllithium in reactions?
While both are strong bases, Di-n-butylmagnesium exhibits different selectivity and reactivity profiles. It is less basic than n-butyllithium but can be preferable for reactions where lithium salts may cause complications.
3. What precautions should be taken when handling this solution?
Handle under an inert atmosphere (nitrogen or argon) using standard Schlenk techniques. Wear appropriate PPE, including gloves and safety goggles, as the solution is pyrophoric and reacts violently with water.
4. Is the heptane solvent anhydrous, and does it require further drying?
The heptane used in this solution is anhydrous and meets synthesis-grade specifications. No additional drying is necessary unless your protocol demands ultra-low moisture levels.
5. How should unused portions of the solution be stored after opening?
Transfer unused solution to a sealed, airtight container under inert gas and store at 2°C–8°C. Avoid repeated opening of the original bottle to prevent contamination.
