Acidity is something that you encounter on a daily basis, probably without even realizing it. The tangy taste of an orange (citric acid), that Vitamin C tablet you took this morning (ascorbic acid), those terrible jeans from the 80’s that you still wear (acid wash). My favourite acid is acetic acid.

Sugar substitutes are gaining more and more relevance due to the health problems associated with the consumption of high amounts of sugar...I thought it would be interesting to take a few of those substitutes and acquire their proton NMR spectrum in our benchtop NMR.

2D NMR experiments provide chemists with evidence to clarify and confirm resonance assignment.  Nowadays every organic chemist uses these experiments called COSY, HMBC and HSQC as routine analytics. Basically, with 2D experiments you correlate some kind of information between two 1D spectra. If we correlate two 1D spectra of the same nucleus we are dealing with homonuclear 2D NMR experiments. The most famous representative of this group is the COSY experiment (find theory here and application here).

Sustainability has become a main focus of innovation.  Topics of green chemistry, and renewable feedstocks, are paramount in society today.  Biodiesel is one such example!  Read more.
