[Analysis Case] Structural Analysis of Natural Products
Introduction of a case where the correlation of 13C-13C could be directly observed through inadequate measurement of 13C-13C!
The 13C-13C INADEQUATE measurement is a method that directly observes the correlation between 13C atoms, providing the advantage of revealing connections between carbon atoms that are not bonded to hydrogen. However, due to the natural abundance of 13C being approximately 1%, the probability of one 13C atom being bonded to another 13C atom is about 0.01%, which presents the drawback of requiring many samples and a long measurement time. Here, we present an example of measuring the natural product andrographolide using a 700MHz NMR with a cryoprobe. 【Case Overview】 ■ Analysis Sample - Andrographolide (heavy dimethyl sulfoxide solution, concentration 100mM) ■ Analysis Equipment - 700MHz NMR with cryoprobe (Bruker AVANCE NEO 700, integration time 24 hours) *For more details, please refer to the PDF document or feel free to contact us.
