analysis

Dissolve a small amount of your purified product and spot it on a final TLC plate. Develop your TLC plate in the appropriate solvent and visualize it using UV light and iodine.

The initial plates showing the starting material and t=0 and t=10 time points are also shown for your reference.
Don't forget to go back and sketch the t=30, t=40, and t=50 plate if you haven't already!

UV light (pencil circles)

photo shows two TLC plates on a lab bench next to a clear plastic ruler whose 0 cm marking is aligned with the origin of the TLC plate; the three lanes on the left TLC plate are labeled, from left to right: “SM,” “t=0,” and “t=10;” the leftmost lane shows a single pencil circle aligned with the 3.3 cm marking on the ruler; the other two lanes show two pencil circles each, one aligned with the 3.3 cm marking and the other aligned with the 2.4 cm marking; the two lanes on the right TLC plate are labeled, from left to right: “pdt" and “SM;” the single pencil circle in the “pdt” lane is aligned with the 3.3 cm marking on the ruler; the single pencil circle in the “SM” lane is aligned with the 3.7 cm marking
