Application

Methyl Acetate serves as a powerful solvent in lacquers, paint strippers, and coating formulations due to its rapid evaporation rate. In pharmaceutical manufacturing, it’s employed as a process solvent for drug synthesis and purification. The chemical finds additional use as a flavoring agent in food products and as a precursor in synthetic organic chemistry. Its low toxicity profile makes it a preferred alternative to more hazardous solvents in many industrial applications.
