WebTHF-d8 impurity I have recently been measuring a few NMRs in THF-d8. All measurements show an impurity at 10.8 ppm. The signal does not couple to any other 1H or 13C signal. A quick check in literature (e.g. Polym. Chem., 2013, 4, 2584, Fig. 3) showed that this signal corresponds to an impurity that is present in the THF-d8.
