Application and positioning

The classic synthetic auxin herbicide and still one of the highest-volume actives for broadleaf control in cereals and turf. Supplied as the technical acid for ester and amine salt formulations; isomer purity and chlorophenol content shape the registration profile. Laurand supplies it from audited Chinese producers in kilogram to tonne lots, with the batch documentation buyers need for registration and incoming QC.

Quality and documentation

  • Batch-specific Certificate of Analysis with active content by HPLC or GC and the relevant impurity profile
  • Water content, acidity and insoluble matter as applicable to the technical grade
  • Analytical methods aligned with CIPAC where a CIPAC method exists for the active ingredient
  • Five-batch trend data and a pre-shipment sample for laboratory confirmation
  • SDS in the language of your market, with GHS classification for the destination

Packaging and handling

  • 25 kg fibre drums or woven bags with inner PE liner; 200 L drums and IBCs for liquid grades
  • Sealed and dry; technical material is hygroscopic in some grades and is packed accordingly
  • Store in a dry, ventilated warehouse away from alkalis, acids and strong oxidising agents
