Ethyl acetate is one of the most commonly used sol- vents in flash chromatography. It is readily available and easy to remove by rotary evaporation. However, ethyl acetate adsorbs in the wavelength range of 200 to 235 nm, a region where many compounds also absorb UV light.

Application

Ethyl acetate absorbs UV light up to about 252 nm. The tan trace shows UV absorption across the full wavelength range, while the black and red traces are specific wavelengths selected for the sample (both are above 252 nm). ... Ethyl acetate has a UV maximum at 210 nm and a UV cutoff beyond 250 nm.
