Application

  • Advanced tetra amino (ATA-100) cobalt(II) phthalocyanine-based metallo-covalent organic polymer: Utilizing butyraldehyde in the synthesis of cobalt(II) phthalocyanine-based polymers, this research provides an innovative approach for detecting volatile organic compounds, presenting significant implications for environmental monitoring and safety assessments in various industries (Güney et al., 2023).
  • Catalytic production of bio-renewable butyl butyrate: This review emphasizes the catalytic use of butyraldehyde for producing butyl butyrate, a potential jet fuel blend, highlighting its role in sustainable fuel development and its importance in the biofuel industry (Kushwaha et al., 2022).
  • Detection of aliphatic aldehydes: A pillar[5]arene-based fluorescent supramolecular polymer demonstrates vaporchromic behavior, which is essential for detecting butyraldehyde among other aldehydes. This technology is crucial for enhancing safety protocols in chemical manufacturing environments (Shi et al., 2022).
