Ethyl acetate ≥99.9%, CHROMASOLV™ for pesticide residue analysis, Riedel-de Haën™

Supplier: Honeywell Research Chemicals

Ethyl Acetate is an organic solvent with the structure CH₃-COO-CH₂-CH₃ (C₄H₈O₂). This colorless liquid has a characteristic sweet odor. In the laboratory, mixtures containing ethyl acetate are used in column chromatography and extractions. Ethyl acetate does not work well as a reaction solvent because it is prone to hydrolysis and transesterification. Ethyl acetate is volatile at room temperature and has a boiling point of 77 °C. Suitable for GC and Pesticide Residue Analysis.
