Optical rotations were measured using a JASCO P-2000 polarimeter with a 1 cm cell. UV spectra were measured with a Varian Cary UV–visible spectrophotometer with a path length of 1 cm, and IR spectra were acquired on a PerkinElmer 1600 FT-IR spectrometer. The 1D and 2D NMR spectroscopic data were obtained on Varian INOVA 500 and JEOL 500 NMR spectrometers. The chemical shift values are reported in ppm units, and coupling constants are reported in Hz. NMR chemical shifts were referenced to the residual solvent peaks (δH 7.25 and δC 77.2 for CDCl3). The high-resolution ESI-TOF mass spectral data were recorded on an Agilent 6530 HR-TOF LCMS. Preparative HPLC separations were performed using a Hewlett-Packard 1050 series with a reversed-phase C-18 column (Phenomenex Luna, 10.0 × 250 mm, 10 μm) at a flow rate of 2.0 mL/min. The HPLC/MS data were obtained using an Agilent 6530 Accurate-Mass Q-TOF spectrometer coupled to an Agilent 1260 LC system with a Phenomenex Luna C18 column (4.6 × 100 mm, 5 μm, flow rate 0.7 mL/min).
1260 lc system
Manufactured by Phenomenex
The 1260 LC system is a liquid chromatography instrument designed for analytical separation and quantification of chemical compounds. It features a solvent delivery system, autosampler, column compartment, and a variety of detectors to provide reliable and reproducible data. The core function of this system is to facilitate the separation, identification, and quantification of analytes in complex mixtures.

The UV spectra were measured with a Beckman Coulter DU800 spectrophotometer with a path length of 1 cm, and IR spectra were acquired on a JASCO FTIR-4100 spectrometer. The 1D and 2D NMR spectroscopic data were obtained on a JEOL 500 NMR spectrometer. The values of the chemical shifts are described in ppm and coupling constants are reported in Hz. The high-resolution ESI-TOF mass spectral data were recorded on an Agilent 6530 Accurate-Mass Q-TOF. The mass spectrometer was coupled to an Agilent 1260 LC system with a Phenomenex Luna C18 column (4.6 × 100 mm, 5 µm, flow rate 0.7 mL/min). Preparative HPLC separations were performed using a Shimadzu SCL-10A with a Shimadzu SPD-M10A UV/Vis detector and a reversed-phase C18 column (Phenomenex Luna, 10.0 × 250 mm, 5 µm) at a flow rate of 3.0 mL/min.
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.
