应用


  • An investigation of o-phthaldialdehyde as a derivatization reagent and optimization of instrumental parameters for qualitative amino acid profiling via UPLC-UV Detailed examination of o-phthaldialdehyde′s efficiency in amino acid profiling to enhance diagnostic accuracies for metabolic diseases like AKU and PKU (A Aspö - 2023). Access the study.

  • Correlation of the Free Amino Nitrogen and Nitrogen by O-Phthaldialdehyde Methods in the Assay of Beer This research correlates nitrogen content measurements in beer using the o-phthaldialdehyde method, discussing its implications for brewing quality control (L Otama, S Tikanoja, H Kane, S Hartikainen, L Kaski - Date not specified). Access the study.

  • Turn-on fluorescence detection of glutathione based on o-phthaldialdehyde-assisted SiO2 particles Investigation into a novel fluorometric method for detecting glutathione in supplements using o-phthaldialdehyde and functionalized silica particles (P Nedeljko, M Turel, A Lobnik - 2018). Access the study.

  • Biochemical Measures of Neuropathy-Glutathione Assay (GSH) A study on the biochemical assessment of neuropathy by measuring glutathione levels using o-phthaldialdehyde in a methanol solution, emphasizing the methodology′s sensitivity and reliability (E Feldman - 2019). Access the study.
