Methyl acetate
Methyl acetate (CAS: 79-20-9), with the linear formula CH₃COOCH₃ and a molecular weight of 74.08 g/mol, is a clear, flammable liquid. It possesses a characteristic fruity odour. As a versatile organic compound, it serves as an important solvent in various industrial applications, including the production of lacquers, plastics, and artificial leather. It is also utilised as a chemical intermediate in synthesis.

Solvent Applications
Methyl acetate is an effective solvent for nitrocellulose, cellulose acetate, and various resins. It is widely used in the formulation of lacquers, enamels, and adhesives due to its moderate evaporation rate and good solvency power.
Chemical Intermediate
This ester serves as a key intermediate in the synthesis of other organic compounds. Its reactivity allows for its use in various esterification and transesterification reactions within the chemical industry.
Extraction Agent
In certain laboratory and industrial processes, methyl acetate can be employed as an extraction solvent, particularly for nonpolar compounds.
Fragrance and Flavour Component
Due to its fruity aroma, methyl acetate finds limited use as a component in certain fragrance and flavour formulations, subject to regulatory compliance.
