General description
Crotonaldehyde(2-Butenal) is an α, β-unsaturated aldehyde and extremely reactive compound. It serves as a chemical building block in the production of solvents, sorbates, and, to a lower extent, pharmaceuticals and aroma compounds. Additionally, it can be used as an alcohol denaturant, in leather tanning and in the manufacturing of rubber accelerators.
Application
Crotonaldehyde is used:
- In the manufacturing of sorbic acid that are widely employed as food preservatives to avoid the food spoilage by microorganisms.

Recent studies have reported that chlorination increased the antiestrogenic activity of wastewater, suggesting that disinfection by-products (DBPs) formed during chlorination is a potential and important source of endocrine-disruptor. However, antiestrogenic DBPs have not been identified. In this study, the antiestrogenic
