Upon completion of the flash chromatography step, the final product is isolated and has to be analyzed.

1. A NMR sample of the product is prepared. If enough material is available, ~0.1 mL of the compound is dissolved in 0.5 mL of deuterated chloroform. The solution placed in a clean NMR tube, which is labeled on the top part with a Sharpie (Name, Chem 30CL, Section, Unknown X). The sample also has to be signed in on a log-sheet provided by the TA. Proper labebling is important in order to provide the correct NMR spectrum to the student later on, and for recovery in terms of further identification e.g. GC/MS.

2. The GC/MS is acquired in a dilute solution. The degree of solution depends on the concentration of the epoxide in the CDCl₃ solution used to acquire the NMR spectra.

3. The small sample quantity usually does not permit to acquire an IR spectrum for the compound.
