SHORT DESCRIPTION
Ethyl Acetate 99.5% Extra Pure is a high-purity solvent widely used in analytical laboratories, chromatography, and sample preparation due to its fast evaporation and low toxicity. In laboratory settings, it’s valued for extraction, purification, and reaction medium roles, especially in organic synthesis. Its low water content and consistent purity make it suitable for GC/HPLC applications, adhesive formulations, and residue analysis. It must be handled in well-ventilated areas, away from heat or flame, and stored in tightly sealed containers to maintain its stability and prevent contamination.
Description
