What is Methyl acetate?

Methyl acetate is an acetate ester resulting from the formal condensation of acetic acid with methanol. A low-boiling (57 C) colourless, flammable liquid, it is used as a solvent for many resins and oils. It has a role as a fragrance, a polar aprotic solvent and an EC 3.4.19.3 (pyroglutamyl-peptidase I) inhibitor. It is a volatile organic compound, a methyl ester and an acetate ester.
