Purification & Characterization
Since a reaction mixture after the completion of reaction contains a small amount of unreacted raw materials and by-products, a purification process is added to isolate the target compound by removing unnecessary components. To monitor these compounds, a simple TLC analysis is concomitantly used. The most common purification method is column chromatography, in which each component is separated due to differences in the degree of interaction with a stationary phase (differences in polarity). A scavenger is also an effective means when removing unnecessary components by using a simple treatment. Presep®, a general-purpose solid phase extraction (SPE) column, is also available.
