Product Overview
Diethyl malonate is a versatile organic compound widely used in laboratory synthesis due to its high reactivity and purity. This clear, colorless liquid features a minimum 99% purity level, ensuring reliable results in ester formation, acid synthesis, and ketone production. Its low moisture content and stable chemical structure make it ideal for applications requiring precise stoichiometric control, such as the preparation of barbiturates, vitamins, and flavor compounds. The reagent’s compatibility with common organic solvents like ethanol and diethyl ether enhances its utility in multi-step reactions. With a boiling point of 199°C and a density of 1.055 g/cm³, it offers consistent performance under standard lab conditions. The 100 ml pack size provides an optimal balance between bulk requirements and storage convenience, minimizing waste while maintaining cost efficiency. Its non-hygroscopic nature ensures long-term stability when stored in a cool, dry environment, away from direct sunlight and oxidizing agents. This synthesis-grade diethyl malonate meets rigorous quality standards, making it a dependable choice for researchers and chemists demanding reproducibility in their experimental workflows.
FAQs
1. What is the typical shelf life of diethyl malonate when stored properly?
When stored in a tightly sealed container at room temperature, away from moisture and light, diethyl malonate maintains its stability for up to 24 months from the date of manufacture.
2. Can this reagent be used directly in aqueous reactions without purification?
While diethyl malonate is highly pure, its hydrophobicity may require the addition of a co-solvent or emulsifier for homogeneous mixing in aqueous systems, depending on the specific reaction conditions.
3. What safety precautions should be taken when handling diethyl malonate?
Always wear nitrile gloves, safety goggles, and work in a fume hood, as the compound can cause skin irritation and releases vapors that may be harmful if inhaled. Avoid contact with strong oxidizers.
4. Is this product compatible with glassware, or does it require special storage containers?
Diethyl malonate is fully compatible with standard borosilicate glass containers. However, for long-term storage, amber glass bottles are recommended to prevent light-induced degradation.
5. How does the purity of this diethyl malonate compare to analytical-grade alternatives?
This synthesis-grade product (99%+) is optimized for reaction efficiency rather than trace analysis. For applications requiring ultra-high purity (e.g., HPLC or GC), analytical-grade variants with 99.9%+ purity would be more suitable.
