WebI read that TLC is often to used to check if a reaction has completed. If I run a reaction with 100% yield, I would expect a clean TLC that indicates if the reaction has finished. I would spot the starting material, the finished material, and a third spot with both. The spot of the finished material would show only one compound. This makes sense. WebApr 18, 2024 · TLC is a common technique in the organic chemistry laboratory because it can give quick and useful information about the purity of a sample and whether or not a reaction in progress is complete. When low polarity solvents are used, a TLC plate can be complete in less than 5 minutes. Assessing Purity
