Application


  • Propanethiol Oxidation Pathway: Propionaldehyde is a critical intermediary in the microbial catabolism of propanethiol, which is essential for environmental bioremediation strategies using Pseudomonas putida. This application in biotechnology suggests promising approaches to industrial waste treatment (Qiao et al., 2024).

  • Chemical Synthesis of mRNA Probes: Propionaldehyde serves as a reagent in the synthesis of modified guanosine phosphate derivatives, which are vital for mRNA labeling in biochemistry and pharmaceutical applications, highlighting its role in advanced molecular biology techniques (Senthilvelan et al., 2023).

  • VOC Treatment in Environmental Engineering: In environmental engineering, propionaldehyde is analyzed as a volatile organic compound (VOC) from service station emissions, underlining its impact on air quality and secondary pollution (Hu et al., 2023).
