General description

Tris(2-butoxyethyl) phosphate is an organic flame retardant. It shows PXR agonistic activity. Tris(2-butoxyethyl) phosphate was detected and quantified during the analysis of herring gull eggs by liquid chromatography-electrospray ionization(+)-tandem mass spectrometry.

Application

  • Monitoring of OPFRs in Environmental Samples: A novel method for the rapid monitoring of organophosphate flame retardants (OPFRs) such as tris(2-butoxyethyl) phosphate in environmental samples was developed, utilizing liquid-liquid extraction and gas chromatography-mass spectrometry. This method aids in assessing the biodegradation of such compounds effectively (Losantos et al., 2024).
  • Presence in Landfill Soil: A case study explored the prevalence of tris(2-butoxyethyl) phosphate in inert landfill soil, highlighting the environmental impact and challenges in managing the disposal of materials containing this chemical (Stelzer et al., 2023).
  • Bioremediation of Contaminated Soil: The study demonstrated that earthworms could enhance the bioremediation of soil contaminated with tris(2-butoxyethyl) phosphate by facilitating the release of degrading microbes, providing a sustainable method to mitigate environmental pollution (Wu et al., 2023).
  • Assessment of Human Exposure to Household Chemicals: Research utilized on-line solid-phase extraction coupled with liquid chromatography-tandem mass spectrometry to assess human exposure to chemicals including tris(2-butoxyethyl) phosphate, commonly found in personal care and household products. This study aids in understanding population-level exposure dynamics (Senta et al., 2022).
  • SVOCs Transmission from Indoors to Outdoors: Investigation into how textile washing conveys semi-volatile organic compounds (SVOCs) like tris(2-butoxyethyl) phosphate from indoor environments to outdoors, using a residential multimedia model to predict environmental dispersion and impact (Kvasnicka et al., 2021).
