For professionals in the chemical industry, understanding the intricate details of key chemical intermediates is fundamental to innovation and efficient production. Diethyl Diethylmalonate, identified by CAS number 77-25-8, is a compound that warrants close attention due to its versatility and importance in various synthetic processes. This article delves into its properties, common applications, and practical guidance on how B2B buyers can effectively source this ester.

Diethyl Diethylmalonate is an organic ester with the molecular formula C11H20O4. It typically presents as a clear, colorless liquid, often described as having a pleasant, fruity, pear-like odor. Its physical properties include a boiling point around 228-230 °C and a density of approximately 0.99 g/mL at 25 °C. Its solubility in common organic solvents like chloroform and methanol makes it amenable to a wide range of chemical reactions. The compound's structure, with two ethyl ester groups attached to a diethyl-substituted carbon atom, provides specific reactivity that is highly prized in organic synthesis.

The primary applications of Diethyl Diethylmalonate are as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Historically, it has been known as a precursor for barbiturates, a class of drugs. In modern industrial chemistry, it continues to be a vital building block for creating complex molecules that form the active ingredients in various medicines and crop protection agents. Beyond these core uses, its ester nature and reactivity also make it relevant in the flavor and fragrance industry, where its unique aroma can be a beneficial component. Researchers also utilize it in general organic synthesis for constructing carbon frameworks and introducing specific functional groups.

For procurement managers and R&D scientists looking to buy Diethyl Diethylmalonate, sourcing from reliable manufacturers is critical. Many suppliers, particularly from China, offer this compound at high purity levels (e.g., 99% or 99.5% minimum assay). When seeking a manufacturer, it's important to look for established companies that provide detailed product specifications, quality certifications, and clear pricing information. Engaging in direct contact with these suppliers, often through their sales departments, is the most effective way to get a quote, understand lead times, and arrange for bulk orders. Packaging typically comes in drums, such as 200kg containers, suitable for industrial quantities.

In essence, Diethyl Diethylmalonate is a foundational chemical intermediate with significant industrial value. Its well-defined properties and broad applicability, especially in the pharmaceutical and agrochemical sectors, make it a sought-after compound. By understanding its characteristics and knowing where to procure it from reputable suppliers, businesses can ensure a steady and quality-assured supply for their manufacturing and research needs.
