Methyl Acetoacetate(CAS: 105-45-3)

Methyl Acetoacetate is an organic compound with the chemical formula C5H8O2. It is a colorless liquid known for its ketone and ester functional groups, characterized by a mild, fruity odor. This compound is commonly used as a building block in chemical synthesis and is recognized for its solubility in organic solvents. Its CAS number is 105-45-3, which identifies it uniquely in chemical databases.

Methyl Acetoacetate finds applications in pharmaceuticals as a precursor for drug synthesis, in industry as a solvent, and in research for organic reactions. It is also used in the production of flavoring agents and as a component in certain polymer formulations. Its versatility makes it valuable in chemical manufacturing and analytical processes. The CAS number 105-45-3 ensures its accurate identification across various sectors.

Methyl Acetoacetate is generally considered safe when handled properly, but it has mild irritant properties. It is classified as a flammable liquid (UN No. 1983), so safety precautions include avoiding inhalation, skin contact, and eye exposure. Proper ventilation, protective gloves, and safety goggles are recommended. It is not classified as carcinogenic, but adherence to OSHA and GHS guidelines is essential for safe use.

Methyl Acetoacetate should be stored in a tightly sealed container in a cool, dry, and well-ventilated area, away from direct light. It is stable at room temperature (20-25°C) but may degrade if exposed to moisture or heat. Storage precautions include keeping it out of reach of children and ensuring compatibility with other chemicals. The CAS number 105-45-3 aids in proper storage identification and safety management.
