Teaching Old Indicators New Tricks: A Colorimetric Chemosensing Ensemble for Tartrate/Malate in Beverages.
The competition between tartrate and a common indicator (1) for a synthetic host (2) has been used to quantitate tartrate in beverages derived from grapes. The approach demonstrates a general method for the development of colorimetric assays in highly competitive media.
