Artemisinin is a drug commonly used to treat malaria. The drug can be produced in a semi-synthetic manner, or it can be extracted from the plant Artemisia annua (sweet wormwood). Figure 1 displays the ...

Since those early days, NMR spectroscopy progressed concurrently with advances in many other fields, such as mathematics, physics and informatics. In the 1960s, the implementation of superconducting ...

NMR spectroscopy is a powerful technique that is ideally suited to the characterization and analysis of a diverse array of chemical compounds. Unlike many other analytical techniques, NMR spectroscopy ...

Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...

Process development is key to identifying the optimal parameters used for synthesis, manufacturing, and stability testing. It is also key to generating the data required for the filing processes of ...
