Application
- Photosensitizer in Synthesis: Discusses diacetyl′s role as a non-toxic, readily available "traceless" photosensitizer in metal-free cross-dehydrogenative coupling reactions, highlighting its versatility and economic benefits (Huang et al., 2019).
- Detection in E-cigarettes: Investigates diacetyl as a precursor to hazardous emissions in e-cigarette liquids, providing insights into the health risks associated with its use in vaping products (Vas, Porter & McAdam, 2019).
- Antimicrobial Activity: Explores the synergistic antimicrobial properties of diacetyl combined with reuterin against foodborne pathogens, emphasizing its potential for enhancing food safety (Langa et al., 2014).
- Coffee Industry Exposure: Details exposure levels to diacetyl and other volatile organic compounds in coffee roasting and café settings, discussing occupational safety measures and health implications (LeBouf et al., 2020).
