Ethyl 2,3-Dicyanopropionate (CAS: 40497-11-8) is a highly active fine chemical intermediate. It appears as a colorless to pale yellow transparent oily liquid at ambient temperature, with molecular formula $\boldsymbol{C_7H_8N_2O_2}$ and molecular weight of 152.15. It serves as an essential core raw material in pesticide and fine synthesis industries.
Featuring dicyano and ester groups in its molecular structure, the product exhibits excellent reactivity and favorable solubility. It is readily soluble in organic solvents such as ethyl acetate and ethers, while barely soluble in water. It acts as a key intermediate for the synthesis of broad-spectrum and high-efficiency insecticides including fipronil. Widely adopted in R&D and mass production of agrochemicals, it is also applied to prepare heterocyclic compounds and fine organic derivatives, fitting synthetic routes for pesticides, new materials and other scenarios.
We maintain strict control over production processes. The product reaches a purity of 99% (GC), with low impurity content and stable acidity. Consistent specifications across batches effectively reduce side reactions in downstream processes and improve the yield and quality of finished products. Purified via multi-stage rectification, it comes with complete test documentation including COA and MSDS, meeting requirements for export, compliance registration and customer quality inspection.
It has stable physical properties: density 1.128 g/cm³, boiling point 132–136℃ (0.5 mmHg) and relatively high flash point for manageable storage and transportation. Packed in sealed drums, it is suitable for long-distance sea shipment and warehousing. Bulk supply is available with flexible production capacity and fast order delivery.
Supported by a mature fine chemical manufacturing system, we provide stable supply, professional technical support and one-stop foreign trade services. We assist customers from sample testing and lab trials to industrial scale-up. Pesticide intermediate manufacturers, research institutes and foreign trade purchasers can enjoy smooth communication and reliable delivery. Premium Ethyl 2,3-Dicyanopropionate ensures stable and controllable downstream synthesis processes and helps boost efficiency for your projects.
