Ethyl Acetate (EA) Cas No. 141-78-6
Ethyl acetate (CH₃COOCH₂CH₃) is a colourless liquid renowned for its sweet, fruity aroma, which is reminiscent of bananas or pears. As a common ester, it has a molar mass of around 88.11 g/mol and a density of 0.902 g/mL at 20 °C, which is less than the density of water. It freezes at -83.6 °C (-118.5 °F) and boils at 77.1 °C (170.8 °F), remaining liquid under typical room conditions. It is slightly soluble in water but highly miscible with organic solvents such as ethanol and acetone, which gives it balanced solubility and enhances its utility across industries.
