Chromatographic Purification and NMR Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
All the reagents and solvents were obtained at the highest commercial quality from sources such as Sigma-Aldrich, Thermo Fisher Scientific, TCI International, etc. Flash chromatography was carried out using a CombiFlash Rf+ Lumen chromatography system (Teledyne ISCO). 1H (400 MHz) and 13C (101 MHz) nuclear magnetic resonance (NMR) spectra were recorded on an Agilent 400-MR NMR, using appropriate deuterated solvents, as needed. Chemical shifts (δ) were reported in parts per million (ppm) upfield from tetramethylsilane (TMS) as an internal standard. LC/MS spectra were recorded on an Agilent 6490 iFunnel Triple Quadrupole Mass Spectrometer from Agilent Technologies Inc.

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.
