  • Nuclear magnetic resonance analysis of a chemically cross-linked ferrous-methylthymol blue-polyvinyl alcohol radiochromic gel dosimeter.: Researchers applied NMR to analyze a ferrous-methylthymol blue-polyvinyl alcohol gel dosimeter, showing its potential for accurate radiation dose measurements in medical and industrial applications (Eyadeh et al., 2019).


  • Discriminate sensing of pyrophosphate using a new tripodal tetramine-based dinuclear Zn(II) complex under an indicator displacement assay approach.: This work presented a novel sensing method for pyrophosphate detection using a Zn(II) complex and methylthymol blue in an indicator displacement assay, highlighting its selectivity and efficiency (Watchasit et al., 2014).


  • Direct colorimetric detection of copper(II) ions in sampling using diffusive gradients in thin-films.: The study introduced a colorimetric technique utilizing methylthymol blue for direct detection of copper(II) ions via diffusive gradients in thin-films, offering a simple and effective analytical tool (McGifford et al., 2010).


  • Experimental correlation between the pKa value of sulfonphthaleins with the nature of the substituents groups.: This research explored the relationship between the pKa values of sulfonphthaleins, including methylthymol blue, and their substituent groups, providing insights for better understanding and predicting their behavior in various chemical environments (Balderas-Hernández et al., 2008).
