NMR spectra were recorded on a Varian Mercury Plus at 400 MHz for 1 H NMR and 100 MHz for 13 C NMR by using TMS as the internal standard. The solvents were CDCl3. HR-ESI-MS was performed on Agilent 6530 Accurate- Mass Q-TOF LC/MS. UV spectra were measured using Thermo Scientific Multiskan GO microplate and cuvette spectrophotometer. IR spectra were run on a Bruker VERTEX 70v FT-IR Spectrophotometer. Column chromatographies were performed on Silica gel 60 (0.063–0.200 mm, Merck) and Sephadex LH-20 (Fluka). TLC was carried out on pre-coated Kieselgel 60 F254 aluminum sheets (Merck).
Kieselgel 60 f254 aluminum sheets
Manufactured by Merck Group
Kieselgel 60 F254 aluminum sheets are a type of thin-layer chromatography (TLC) support material. They consist of a uniform layer of silica gel (Kieselgel 60) coated onto an aluminum backing, with the addition of a fluorescent indicator (F254) for visualization purposes. This product is commonly used in analytical chemistry applications that require the separation and identification of compounds through TLC techniques.

Mass spectral data (TOF-ESI-MS + ) were obtained from a Q-TOF Ultima spectrometer (Waters). 1 H (500 MHz) and 13 C NMR (125 MHz) spectra were run on a Bruker Avance AV-500 spectrometer using TMS as internal standard, chemical shifts being quoted in parts per million (ppm) . The solvents used to dissolve compounds for the NMR experiment were DMSO-d6, CD3OD or CDCl3; For column chromatography separations, silica gel Merck 60 was used. Thin-layer chromatography was performed on pre-coated Kieselgel 60 F254 aluminum sheets (Merck) and spots were detected under ultraviolet uorescence and then sprayed with 10% H2O-H2SO4 reagent, followed by heating at 105°C for 10 mins.
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.
