Malononitrile, identified by its CAS number 109-77-3, is a fundamental organic compound celebrated for its reactivity and versatility as a chemical intermediate. For procurement managers and R&D scientists in various industries, a thorough understanding of its properties is crucial for successful application and sourcing. As a leading manufacturer and supplier, we aim to provide insights into why Malononitrile is indispensable and how our offerings from China meet global demands.

The primary utility of Malononitrile (CH2(CN)2) stems from its unique molecular structure. It features a methylene group (-CH2-) situated between two electron-withdrawing nitrile groups (-CN). This arrangement significantly increases the acidity of the methylene protons, giving Malononitrile a pKa of approximately 11 in water. This heightened acidity makes it highly reactive in Knoevenagel condensations, Michael additions, and other base-catalyzed reactions, allowing it to readily form new carbon-carbon bonds. This reactivity is key to its use in synthesizing pharmaceuticals, dyes, and advanced materials.

Examining its physical properties, Malononitrile typically appears as a colorless or white crystalline solid. Its melting point is reported to be around 30-32 °C, and its boiling point is approximately 218.5 °C at atmospheric pressure. These properties indicate that while it is a solid at room temperature, it can be easily melted or dissolved for reaction processes. The Flash Point of 112.2 °C suggests moderate flammability. For industrial users, understanding these physical and chemical properties is vital for safe handling, efficient processing, and successful synthesis outcomes. If you are looking to buy Malononitrile, ensuring these specifications are met is paramount.

The applications of Malononitrile are broad, ranging from the synthesis of vitamins like thiamine and drugs such as triamterene, to the production of vibrant dyes and specific electronic chemicals. Its role as a building block means that its quality directly impacts the final product. Therefore, sourcing from a reliable manufacturer that guarantees high purity (assay min. 99.0%) and stable supply is essential. Chinese manufacturers have become key players in providing these critical intermediates at competitive prices, making them an attractive option for global procurement.

In conclusion, Malononitrile (CAS 109-77-3) is a chemical workhorse whose unique properties drive innovation across multiple industries. Its reactivity and accessible chemical characteristics make it a highly sought-after intermediate.
