Chemical name:1,2-dihydropyridazine-3,6-dione Appearance:white crystal Assay:95%、98% Melting point:299-301 °C (dec.)(lit.) Density: 1,6 g/cm3 Flash point:300°C Loss on dry: ≤1.0% Residue on ignition:≤0.2% About 3,6-Dihydroxypyridazine CAS 123-33-1:
It is selective herbicides and temporary plant growth inhibitor in agriculture. The agent can enter the plant through the leaf cuticle, reducing photosynthesis, osmotic pressure and evaporation, effectively prevent bud growth. It can be used in potato, onion, garlic and radish at the storage period to prevent germination degeneration, and to inhibit the growth of crops and prolong the flowering. It can also be used for non-cultivated land weeding. It is an intermediate of the sulfa drug sulfamethoxypyridazine.
3,6-Dihydroxypyridazine is a plant growth regulator. Inhalation through the the leaf surface or roots, conduction from the xylem and phloem, inhibiting cell division and inhibiting plant growth. 0.1%~0.05% drug liquid can inhibit the grass, lawn, hedge and weeds growth. 0.025% solution inhibits onion and potato germination during storage. 0.1%~0.05% solution inhibits and delays tobacco side bud growth and maintains citrus seedlings protect from frost.
