Product Overview

Allylmagnesium bromide is a highly reactive 1M solution in diethyl ether, packaged under the AcroSeal® brand to ensure maximum purity and stability for critical organic synthesis applications. This Grignard reagent features a standardized concentration of 1.0M (±0.05M), providing consistent performance in allylation reactions, carbon-carbon bond formation, and nucleophilic addition processes. The ether solvent system enhances solubility while maintaining reagent stability during storage when handled under inert conditions. Designed for researchers requiring precise stoichiometry, this solution undergoes rigorous quality control to eliminate trace impurities that could compromise reaction yields. The AcroSeal® packaging incorporates a PTFE-lined septum cap to prevent moisture ingress and solvent evaporation, with each batch accompanied by a certificate of analysis verifying the molar concentration and absence of common contaminants like magnesium bromide or oxidation byproducts. Ideal for applications demanding high reproducibility, this reagent offers superior batch-to-batch consistency compared to in-house prepared alternatives. The solution’s pale yellow to colorless appearance serves as a visual indicator of its freshness and proper storage conditions.

FAQs

1. What is the typical shelf life of Allylmagnesium bromide 1M solution when stored properly?

The solution maintains its specified concentration for 12-18 months when stored at 2-8°C under nitrogen and protected from light. Regular titration is recommended for critical applications.

2. Can this reagent be used directly without titration for standard allylation reactions?

While the 1M concentration is standardized, we recommend verifying the exact molarity via titration before use in quantitative reactions, as minor variations may occur during storage.

3. What are the key safety precautions when handling this ether solution?

Use in a properly ventilated fume hood with nitrogen atmosphere. The ether solvent is highly flammable, and the reagent reacts violently with water, releasing hydrogen gas.

4. How does the AcroSeal® packaging differ from standard reagent bottles?

The AcroSeal® system features a PTFE-lined septum cap and nitrogen headspace to prevent moisture contamination and solvent loss, unlike traditional screw-cap bottles.

5. What analytical methods are used to verify the 1M concentration?

Each batch is standardized via acid-base titration against a primary standard, with results documented in the accompanying certificate of analysis.
