500 mhz nmr
The 500 MHz NMR is a nuclear magnetic resonance spectrometer that operates at a frequency of 500 MHz. It is designed to analyze the molecular structure of chemical compounds by detecting the magnetic properties of their nuclei.

THF.90 For 31P NMR, nondeuterated
THF90 was used while disabling the lock
function. The 13C and 31P NMR measurements were
performed with routine pulse programs and proton decoupling. The samples
were measured on a Varian 500 MHz NMR with the external standard ClPPh2 (neat liquid, δ(31P) = +81.92 ppm) for 31P and the solvent signals for 13C. The 31P NMR spectra were typically obtained with satisfactory S/N ratio
with 128 or 256 scans. Line broadening factors of up to 10 Hz were
applied as needed.

Non-commercially available MUFAs were synthesised as described in the supporting information. The purity of all test compounds (3 -20) was confirmed by elemental analysis carried out in the Campbell Microanalytical Laboratory at the Department of Chemistry, University of Otago. All values were within ±0.4% of the calculated values.
Dry Column Vacuum Chromatography (DCVC) was used to purify reaction products on silica gel with gradient elutions. TLC was performed on silica gel 60 F254 plates. 1 H and 13 C NMR spectra were recorded on an Agilent 500 MHz NMR. Spectra were referenced internally to residual solvent (CDCl3; 1 H 7.26, 13 C 77.10. d6-DMSO; 1 H 2.49, 13 C 39.52). High resolution mass spectra were recorded on Agilent 6510 Q-TOF LC/MS.
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.
