Beschreibung

General description

Ethyl acetate is a volatile, moderately polar solvent widely used in analytical chromatography. Its high purity, low UV absorbance, and compatibility with aqueous and organic phases make it suitable for HPLC, GC, and pharmaceutical testing. Meeting ACS and USP/NF specifications ensures its reliability in regulated environments and compendial methods.

Application

EX0245P-1 is packaged in poly coated glass bottles
EX0245-NP10 is sold as 2 x 10 L

Ethyl acetate can be used as a:

• Mobile phase component in normal-phase HPLC for separating non-polar and moderately polar compounds, especially in pharmaceutical and food analysis.
• Sample preparation solvent for volatile and semi-volatile organic compounds due to its rapid evaporation and clean baseline characteristics.

Packaging

M-Bottle for Solvents
