All NMR spectroscopy measurements were performed with a Bruker Avance III 500 spectrometer operating at 500.13 MHz for 1H, 125.75 MHz for 13C, and 202.45 MHz for 31P at 22 °C. Mass spectra were recorded with an Agilent 6520 Q‐TOF LC–MS (HRMS). FTIR spectra were recorded with ATI Mattson Infinity Series AR60, ThermoScientific Nicolet 6700 ATR, and Bruker Alpha‐P ATR spectrometers. All products were stored in a refrigerator (4 °C).
6520 q tof lc ms hrms
Manufactured by Agilent Technologies
The 6520 Q‐TOF LC–MS (HRMS) is a high-resolution mass spectrometry instrument designed for accurate mass measurements and precise qualitative and quantitative analysis. It combines a quadrupole time-of-flight (Q-TOF) mass analyzer with liquid chromatography (LC) for separation of complex sample mixtures.

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.
