Ethyl 2 3-dicyanopropionate CAS 40497-11-8

1. Serves as a key intermediate in organic synthesis, widely used in the preparation of heterocyclic compounds (such as pyridines, pyrazoles, and triazoles), which are essential building blocks for pharmaceuticals, agrochemicals, and fine chemicals.
2. Applied Ethyl 2 3-dicyanopropionate CAS 40497-11-8 in the synthesis of bioactive molecules and pharmaceutical intermediates, including antiviral, antibacterial, and anti-inflammatory drug candidates, leveraging its dicyano and ester functional groups for versatile chemical transformations.
3. Used in the production of specialty chemicals, such as dyes, pigments, and polymer monomers, and also acts as a reagent in Michael addition and condensation reactions to construct complex organic structures.

1. Store in a cool, dry, well-ventilated area at 10-20℃, away from direct sunlight, heat sources, and open flames to prevent decomposition, discoloration, or polymerization of the product.
2. Keep Ethyl 2 3-dicyanopropionate CAS 40497-11-8 the container tightly sealed to avoid contact with air, moisture, and acidic or alkaline substances, as these may trigger hydrolysis or other unwanted reactions that reduce product purity.
3. Operate in a fume hood with adequate ventilation, wear chemical-resistant gloves, safety goggles, and a lab coat; avoid direct skin and eye contact, and use dry, anhydrous equipment during handling to prevent hydrolysis.

1. Causes severe skin and eye irritation; contact with skin may lead to redness, burning, and blistering, while eye contact can cause severe pain, inflammation, and potential tissue damage if not treated promptly.
2. Harmful Ethyl 2 3-dicyanopropionate CAS 40497-11-8 if inhaled or swallowed; inhalation of vapor or mist may cause respiratory tract irritation, dizziness, and nausea, and ingestion can lead to gastrointestinal distress, vomiting, and abdominal pain.
3. In case of skin contact, immediately remove contaminated clothing and rinse the affected area with plenty of running water for at least 15 minutes; in case of eye contact, rinse cautiously with water for several minutes, remove contact lenses if present, and continue rinsing before seeking medical attention.

1. Possesses two cyano groups (-CN) and one ester group (-COOEt), which exhibit high reactivity and can participate in a variety of organic reactions, including nucleophilic addition, substitution, and cyclization, enabling efficient synthesis of complex molecules.
2. Exhibits Ethyl 2 3-dicyanopropionate CAS 40497-11-8 good solubility in common organic solvents (e.g., dichloromethane, ethyl acetate, toluene), compatible with diverse reaction systems, and does not produce significant by-products, ensuring clean and high-yield synthesis.
3. Has a stable chemical structure under mild reaction conditions, is easy to handle and store, and is cost-effective, making it suitable for both laboratory research and large-scale industrial production.
