Ethyl acetoacetate (CAS No.: 141-97-9) is a colorless transparent liquid with an aromatic odor. As a classic ester compound, it features stable molecular structure and can be stored for a long time under normal temperature and pressure. The product exhibits keto-enol tautomerism characteristics: the keto form accounts for 93% and the enol form for 7% in freshly distilled products. It shows a characteristic purple color when reacted with ferric chloride, making it a highly valuable basic intermediate in the field of organic synthesis. With low toxicity (LD50 of 3980 mg/kg via oral administration in rats) and unique bacterial biofilm inhibitory activity, it finds wide applications in industrial production and scientific research.
Melting point of -43℃, boiling point of 180.6℃ (at 760 mmHg), density of 1.0±0.1 g/cm³, flash point of 67.0℃. It possesses good solubility and stability, slightly soluble in water (solubility of 116 g/L at 20℃) and miscible with most organic solvents such as alcohols and ethers.
Prone to hydrolysis, reduction and other reactions. Under dilute acid or dilute alkali conditions, it can produce acetone, ethanol and other products; catalytic reduction yields β-hydroxybutyric acid, enabling diverse synthetic reactions.
Classified as a low-toxicity compound. Although it has mild irritancy and anesthetic effects, safe operation can be achieved through standardized protection. It has no polymerization hazard, and its decomposition products are only carbon monoxide and carbon dioxide, resulting in controllable environmental impact.
Industrial-grade products have a purity of over 97%. Key indicators such as molecular weight (130.142) and molecular formula (C₆H₁₀O₃) comply with international general standards, ensuring strong batch stability.
As a core raw material for synthesis, it is widely used in the preparation of various fine chemicals, including heterocyclic compounds, fragrances, coating additives, etc., serving as a key link in constructing complex molecular structures.
Used in the synthesis of various colorants in the dye industry; in the pharmaceutical field, it can be used as a synthetic precursor for antibacterial-related drugs. Its bacterial biofilm inhibitory activity provides support for the research and development of anti-infective products.
Can be used as the organic substrate for the Belousov-Zhabotinskii oscillating reaction, and also for the synthesis research of β-glucuronidase inhibitors, making it a common reagent in the fields of chemical kinetics and drug development.
Can be used in the preparation of resins, plastic modifiers and other materials. Its unique physicochemical properties can improve the processing performance and application effects of products.
Packaged in aluminum drums with excellent sealing performance to ensure no leakage during transportation and storage. The packaging grade meets the requirements of Class III dangerous goods.
Hazardous goods transport code UN 1993. During transportation, it is strictly prohibited to mix with oxidants, reducing agents, acids, alkalis and food chemicals. Vehicles and ships must be thoroughly cleaned and disinfected before loading and unloading. For sea transportation, the loading position should be away from bedrooms, kitchens and other areas; road transportation must follow designated routes.
Should be stored in a cool and well-ventilated warehouse, away from fire sources and heat sources, with the warehouse temperature controlled within an appropriate range. Store separately from incompatible chemicals, equip with sufficient fire-fighting equipment and leakage emergency treatment equipment, and prepare sand and other containment materials in the storage area.
Operators must receive professional training and wear self-priming filter-type gas masks (half-mask), chemical safety goggles, poison-proof permeable work clothes and rubber oil-resistant gloves. Smoking is strictly prohibited in the workplace; use explosion-proof ventilation systems and equipment.
