Extraction and presentation

Fenfuram can be obtained from glycolaldehyde and acetoacetic acid. These react to form 2-methylfurancarboxylic acid, which reacts with thionyl chloride and aniline to form fenfuram.

use

Fenfuram is used as a systemic seed treatment in grain cultivation.

Admission

Fenfuram was approved in Germany from 1978 to 2002.
