Metalaxyl (S)-enantiomer is the S-enantiomer of the widely used acetylalanine fungicide― metalaxyl. A systemic pesticide, it targets the RNA polymerase complex I and inhibits the synthesis of ribosomal RNA. It shows protective and curative abilities after its absorption through roots, stalks, and leaves.
As per Regulation (EC) No. 1107/2009, repealing directive 91/414/EEC, metalaxyl is approved for use as a plant protection agent in the European Union. The Reg. (EU) 2017/1164 sets a maximum residue limit (MRL) of 0.7 mg/kg and 0.01 mg/kg for the presence of metalaxyl in fresh/frozen fruits and tree nuts respectively, considering other mixtures of its constituent isomers including metalaxyl-M (sum of isomers). It is also included for monitoring in the Multiannual Control Programme for Pesticides Residues (MACP), run within the EU and EFTA for products of plant origin.

Application

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
