Application:

  • Simultaneous determination of legacy and emerging organophosphorus flame retardants and plasticizers: This study highlights the use of Bis(2-ethylhexyl) terephthalate in analytical chemistry, particularly in liquid and gas chromatography-tandem mass spectrometry for the detection of plasticizers in indoor dust. This application underscores its significance in environmental monitoring and safety evaluations (Christia et al., 2019 ).

  • Critical evaluation of several techniques for the analysis of phthalates and terephthalates: This research focuses on various analytical methods, including the use of Bis(2-ethylhexyl) terephthalate, for analyzing liquids used in electronic cigarettes. The study assesses the effectiveness of different techniques in detecting phthalates and terephthalates, contributing to safer product standards in the e-cigarette industry (Moldoveanu and Yerabolu, 2018 ).
