What Is Triazinamide Used For in Pesticide Manufacturing
Core Function
Triazinamide (CAS 136738-23-3, alias P4) is the key upstream intermediate for synthesizing pymetrozine, a systemic selective insecticide widely used in global agrochemical factories.
Full Synthetic Workflow Role
- Deacetylation StepIts acetylamino group undergoes acid hydrolysis to produce amino-triazinone, the core triazinone parent scaffold of pymetrozine.
- Final Condensation ReactionAmino-triazinone reacts with nicotinaldehyde to cyclize and form technical-grade pymetrozine raw drug, with high industrial yield up to 91%–96%.
Target Pest & Crop of End Product Pymetrozine
Pymetrozine controls piercing-sucking pests: aphids, planthoppers, whiteflies, leafhoppers on rice, wheat, vegetables, cotton and fruit trees. It blocks insect feeding without rapid knockdown, low toxicity to pollinators and crops.
Extra Industrial Applications
- Lab raw material for developing novel 1,2,4-triazinone pesticide analogues
- Minor auxiliary intermediate for fine chemical & pharmaceutical heterocycle synthesis
