Purification and Characterization of Nilotinib

Check if the same lab product or an alternative is used in the 5 most similar protocols
Solvents used were puriss, with the exception of THF, which was purified by fresh distillation over Na/benzophenone. Commercially available reagents were used as received, without any further purification. Nilotinib was purchased from Selleck Chemicals, Munich, Germany. Analytical TLC was performed on commercial Merck silica gel 60 F254. Flash chromatography was carried out using silica gel 60 (230–400 mesh). HPLC experiments were performed using a Shimadzu system, consisting of a DGU-20A controller, an LC-20AD pump, an SPD-M20A photodiode-array detector and a CTO-10AS column oven. 1H and 13C NMR spectra were recorded on a Brucker AMX (400/100 MHz 1H/13C) spectrometer using tetramethyl silane (TMS) as an internal standard. Chemical shifts are reported in ppm (δ) referenced to TMS, coupling constants J in Hz. High-resolution ESI mass spectra were measured on a Thermo Fisher Scientific LTQ ORBITRAP/LC−MS system. Elemental analyses were performed on a Heraeus CHN-Rapid Analyser.

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.
