Case Study

Manufacture of a key intermediate for a novel agrochemical active

  • For a six step synthesis from lab to pilot scale, process development for the final three steps was performed concurrently with piloting of the first three steps
  • Flexible combination of standard and new chemical reactions
  • 4 months from contracting to delivery of 2’000 kg product
  • our Asian competitor failed to deliver the other component of the target molecule
Case Study

Custom synthesis of an agrochemical intermediate for a new active

  • Three step Synthesis with distillation rectification with stringent quality requirements
  • 15 weeks from start of lab work until supply of > 10 tonnes from production plant
  • Immediate yield improvement by 6 %; further measures identified which will be implemented in the first two campaigns, leading to a total yield improvement of 23 % over lab results
