Ethyl Acetate ACS

Product Overview

Alliance Chemical supplies Ethyl Acetate ACS Grade, a high-purity colorless liquid ester widely utilized as a premium solvent in analytical chemistry and industrial processing. Also known as Ethyl Ethanoate, this product features an assay of ≥99.5%, ensuring minimal residue and strict impurity controls required for critical applications.

With a low boiling point and excellent solvency, Ethyl Acetate ACS is specifically formulated for use in HPLC mobile phases, column chromatography, and precise extractions. It effectively dissolves resins, adhesives, and organic compounds, making it a staple in coating formulations and laboratory workflows. This grade is rigorously tested for trace metals and aldehydes to prevent interference in sensitive analytical methods.

Safety & Handling

Ethyl Acetate is a flammable liquid and vapor. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep containers tightly closed to prevent evaporation. Personnel should wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and splash goggles. Ensure adequate ventilation or exhaust systems are in place during use to keep vapor concentrations below exposure limits.
