Application



  • Synthesis and characterization of various organic fluorescent and thermally stable polyesters with s-triazine frame and bulky side chain: This study highlights the use of benzilic acid as a bulky pendant group contributing to the fluorescence and thermal stability of polyesters (JV Modh, SA Pillai - CURRENT SCIENCE, 2023). Access the paper.


  • Simultaneous Determination of 13 α-Hydroxy Acids in Cosmetics by Ultra-High Performance Liquid Chromatography Triple Quadrupole Mass Spectrometry: Discusses the quantification of benzilic acid among other α-hydroxy acids in cosmetics, highlighting its importance in skincare products (高天阳 et al. - Physical Testing and Chemical Analysis Part B: Chemical Analysis, 2023). Access the paper.


  • Exploiting benzilic acid as a modular template: controlling photoreactivity and solid to liquid transition during photodimerization: This research uses benzilic acid as a core component to explore controlled photoreactivity and phase transitions in synthesized materials (MR Ahsan et al. - Chemical Communications, 2023). Access the paper.


  • Multicomponent Cyclizative 1, 2‐Rearrangement Enabled Enantioselective Construction of 2, 2‐Disubstituted Pyrrolinones: Reports a novel benzilic acid-type rearrangement in the synthesis of complex organic molecules, enhancing the enantioselectivity of the process (XZ Li et al. - Angewandte Chemie, 2024).
