Parabens are widely used preservatives in food, cosmetics, & pharmaceuticals. Due to their presence in consumer products, methods to determine their purity are important. The current methods using HPLC are powerful, but wasteful and inefficient. In this blog post, we showcase the use of benchtop NMR to quantify the purity of 3 different parabens & demonstrate that this approach is quicker & far less expensive than the traditional methods currently used in industry.

In this blog post we show a simple experiment that teaches student how common over the counter (OTC) medications can be qualified and quantified for their different active pharmaceutical ingredients (API) using qNMR spectroscopy.

In the average case one can simply dissolve an analyte in an appropriate deuterated solvent and acquire a simple 1D spectrum to obtain all the required structural information. However, sometimes doing so may not provide you with all of the information you need!
