The occurrence in groundwater of the Chlorothalonil Metabolite R471811 remained undetected for a long time. However, current investigations show that this degradation product of the fungicide chlorothalonil is detected in groundwater with concentrations >100 ng/L.

Based on current data, chlorothalonil degradation products are considered to be relevant intermediates. A limit value of 100 ng/L must therefore be applied to drinking water.

For your investigations, we can offer you Chlorothalonil Metabolite R471811 as sodium salt.

This substance is available from stock. We look forward to your inquiry.
