NMR Spectroscopy of Isolated Compounds

Check if the same lab product or an alternative is used in the 5 most similar protocols
The NMR spectra of the isolated compounds were recorded using an AV III 300 (300 MHz) and a DRX-600 (600 MHz) instrument (Bruker Daltonik, Billerica, MA, USA). The solvents used were chloroform-d1 and acetone-d6 from Eurisotop (Saint-Aubin, France). The spectra obtained were referenced using the residual signals (CDCl3: δ (1H) = 7.26 ppm and δ(13C) = 77.16 ppm; acetone-d6: δ (1H) = 2.05 ppm and δ(13C) = 29.84 ppm). MestreNova 14.2.1 purchased from Mestrelab Research S.L. (Santiago de Compostela, Spain) was used to process the spectra.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
