Congratulations to John Frost, Jessica Bonjour and Joy Pitzer for their recent publication in the Journal of Chemical Education. The article reviews the implementation of NMR spectroscopy into the (U.S.) high school or first year college undergraduate curriculum. This article presents a simple laboratory experiment using benchtop NMR to determine the percent composition in a series of household solutions explored with high school honors chemistry students.
Aspirin (C9H8O4), acetylsalicylic acid, is a salicylate drug used to treat a variety of conditions, including headaches, fever and inflammation. It is also used in low doses in preventive treatment against heart attacks, strokes and blood clots.
The 1H NMR spectrum of a 4% (w/w; 330 mM) solution of aspirin in chloroform-D was measured at 82 MHz using the Thermo Scientific™ picoSpin™ 80 NMR spectrometer.
Flow chemistry is a widely accepted technique in the synthesis field and makes optimization fast and convenient. Using a benchtop NMR instrument allows chemists to measure 1H NMR spectra directly in the fume hood and monitor pseudo real-time behavior of reaction chemistries.
Read this application note from ThalesNano to get details on both the flow synthesis at extremely high temperature as well as the following analysis.
Butanol, C4H9OH, is a high value C4 alcohol collectively represented by fopur isometric structures: 1-butanol, 2-butanol, isobutanol and tert-butanol. Isomers are compounds that have the same molecular formular but which the connectivity of the atoms differ.
(±)-Propranolol hydrochloride (C16H21NO2 · HCl), a nonselective beta-blocker, is representative of a class of drugs that target the beta receptor. It is prescribed medication for treatment of hypertension, severe headaches, and cardiac related dysrhythmia and ischemia.
The 1H NMR spectrum of a 11.2% (w/w; 420 mM) solution of propranolol in protonated DMSO was measured at 82 MHz using the Thermo Scientific™ picoSpin™ 80 spectrometer.
