Empirical formula: C9H13ClN6
Structural formula:
Molecular mass: 240.70
Basic chemical and physical data: The pure Cyanazine is white crystal, m.p. 167.5 – 169℃, vapor pressure 0.21x10-6Pa at 20℃. Solubility in water: 171mg/L (25℃); solubility in organic solvents (25℃): 15g/L in benzene; 210g/L in chloroform; 45g/L in ethanol; 15g/L in hexane. This material is stable to light and heat. It will hydrolyze in neutral, slightly acidic, or slightly basic conditions. This material is non-flammable, non-explosive, and non-corrosive.
Usage: Cyanazine is used to control the broad leaf weeds and gramineous weeds in the fields of maize, pea, horsebean, potato, sugarcane, cotton etc.
Toxicity: The acute oral LD50 for rats is 182mg/kg, the acute dermal LD50 for rats is 1200mg/kg. It is low toxic to fish.
Storage: Cyanazine shall be stored in a cool, dry and well ventilated place. It should not be stored or transported along with foods.
Package: 25kg woven bag, or 500kg big-bag, or according to the customer’s requirements.
Attention: 1. The rain or irrigation after application will enhance the effect. 2. It is not safe to maize at low temperature or high humidity in air. 3. The temperature of 15 – 30℃ will be best for the application to leaf; the surfactant will enhance the effect when it is droughy.
