Question

In Organic Chemistry lab, we took one compound, performed an EAS, then ran it through an HPLC.

Information I have: Crude Product HPLC readings with two peaks and no standards shown, Purified product HPLC reading with two peaks showing an obvious purification and only a little bit of the compound left behind and area readings for all, I also have an IR spectrum of ONLY the purified product, and I also have NMR for the two compounds involved in the products with no specification of when the NMR was taken (I think they're samples). I have identified the products.

My question might be really simple and stupid. I might be compltely overthinking it. Or I might not.

My question: How do I find the ratio of the products before purification and then the ratio of products after purification? TA said something about a ratio from NMR, but I don't think I heard that right since I only have sample NMR for the two compounds. Do I use the HPLC since I have numbers of before and after? Is area and concentration from HPLC somehow involved? We didn't find the mass of the unpurified product so I don't think comparing masses is the right track. So I think maybe HPLC is somehow involved? If you can tell me how you come up with the answer, that will help me understand it better. Thank you so much!

Explanation / Answer

I thik you can calculate the ratio from the HPLC, where you have the area for all, before sepration and after sepration.
