Methyl acetoacetate is a core raw material for organic synthesis with a clear chemical structure and stable performance. Its chemical formula is C₅H₈O₃, CAS number is 105-45-3, and molecular weight is 116.115. It appears as a colorless transparent liquid with a unique aromatic odor, combining the solubility of solvents and the reactivity of synthetic intermediates. As a low-toxic and flammable chemical, it can be widely used in various industrial production and organic synthesis scenarios under the premise of strictly following safety specifications. The product is processed through professional precision refining technology to effectively remove impurities such as free acids, alcohols and acetone, and its purity and stability are more in line with industrial-grade application standards.
Density is about 1.0±0.1 g/cm³, boiling point is 169.4±8.0℃, melting point is as low as -28℃. It is stable under normal temperature and pressure, facilitating storage and process operation.
Slightly soluble in water (solubility 460 g/L at 20℃) and easily compatible with various organic solvents. It can be used as a single solvent or as a component of mixed solvents to adapt to multi-component systems.
It can maintain stability when avoiding contact with oxidants and alkalis, and shows a characteristic deep red color when encountering ferric chloride. With strong reaction selectivity, it is a high-quality intermediate for precise synthesis of target products.
It belongs to the low-toxic category, with LD₅₀ of more than 3000mg/kg for oral administration in rats and controllable irritancy. Operational safety can be guaranteed through standardized protection.
As a key intermediate, it can be used to prepare a variety of high-efficiency pesticide products such as fungicides (hymexazol, dimethirimol), insecticides (diazinon, coumaphos), herbicides (imazethapyr) and rodenticides (coumatetralyl), supporting agricultural pest control.
It is an important raw material for pharmaceutical synthesis, widely involved in the preparation of various pharmaceutical intermediates, and provides basic support for the research and development and production of antibacterial, anti-inflammatory and other drugs.
Suitable for cellulose ether and cellulose resin systems, it can be used as a special solvent or mixed solvent component to improve material dissolution efficiency and system stability.
Used in the organic synthesis of dyes, polymer stabilizers and other products, it optimizes the synthesis process and improves the performance of end products by virtue of its good reactivity.
Adopt aluminum drum packaging with excellent sealing performance to ensure tight and leak-proof drum lids and prevent volatilization and pollution during transportation.
Strictly prohibited from mixed transportation with oxidants, alkalis, food chemicals, etc., to avoid safety risks caused by chemical reactions.
Check the integrity of packaging before transportation, and ensure that the containers are free from leakage, collapse and damage during transportation; vehicles and ships must be thoroughly cleaned and disinfected before loading and unloading. For ship transportation, it should be far away from bedrooms, kitchens, fire sources and power sources, and follow the specified routes for road transportation.
Transport vehicles should be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment. In case of leakage, it can be disposed of by sand adsorption or large amount of water flushing.
