The structures of the Sit derivatives were established by IR and NMR analysis. The NMR spectra were recorded on a Varian Mercury 300 MHz NMR spectrometer equipped with an Oxford Instruments Ltd. superconducting magnet (Palo Alto, CA, USA). FTIR analysis was performed in a WGH-30A double beam infrared spectrophotometer (Gangdong Sci. & Tech. development Co., Ltd. Tianjin, China). The specific conclusion is described in detail in the Results section.
Mercury 300 mhz nmr spectrometer

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.
