Application


  • Anionic polymerization initiator synthesis: Research on mono-lithium based initiators for polybutadiene synthesis highlights the steric effects of TBDMSCl as a component (Zhu et al., 2017).

  • Environmental analysis: TBDMSCl is used in the analysis of bisphenol compounds in wastewater, indicating its role in complex sample preparation processes (Cesen et al., 2018).

  • Derivatization in chemical analysis: The reagent is utilized for in situ derivatization extraction techniques for detecting nerve agent degradation products (Chinthakindi et al., 2014).
