Descrizione

Applicazioni

• Heptafluorobutyric acid in peptide modification analysis: A study discussed the application of heptafluorobutyric acid in the retention time prediction for post-translationally modified peptides. This research facilitates the analysis of phosphorylated peptides in biological samples, enhancing the accuracy and efficiency of proteomic studies (Battellino et al., 2024).
• Environmental monitoring of perfluorinated compounds: Heptafluorobutyric acid was used in a method involving in-source fragmentation for the identification of perfluoropentanoic acid and perfluorobutanoic acid in environmental matrices and human serum. This application highlights its role in environmental health studies and pollution monitoring (Yu et al., 2023).
• Synthesis and adsorption studies: Heptafluorobutyric acid is highlighted in the synthesis and evaluation of spherical amino-functionalized covalent organic frameworks for the adsorption of perfluorinated compounds. This illustrates its importance in the development of materials aimed at environmental remediation (Ye et al., 2023).
