Alachlor ESA

Description:

Alachlor ESA, or alachlor ethane sulfonic acid, is a metabolite of the herbicide alachlor, primarily used for controlling weeds in various crops. It is characterized by its chemical structure, which includes an ethane sulfonic acid group, making it a polar compound. This polarity influences its solubility in water, allowing it to be mobile in soil and potentially leach into groundwater. Alachlor ESA is known for its persistence in the environment, which raises concerns regarding its ecological impact and potential effects on human health. It is typically analyzed in environmental samples to assess contamination levels, particularly in agricultural areas. The substance is subject to regulatory scrutiny due to its classification as a possible human carcinogen, necessitating careful monitoring and management in agricultural practices. Overall, Alachlor ESA serves as an important marker for understanding the environmental fate of alachlor and its implications for agricultural sustainability and safety.
