There are uses for the adaptable dye thymol blue sodium salt in both chemistry and biology. Staining fatty acids is one of its main applications. When it interacts with fatty acids, a color shift occurs that can be used to detect or measure the amount of fatty acids in a sample. Although the precise mechanism of this interaction is still being studied, non-covalent interactions between the dye and the molecules of fatty acids are probably involved. Thymol blue is useful in a variety of study fields, including biochemistry and lipid analysis.
