Usage and Synthesis

Chemical properties:
white granular crystals. clorpyrifos has a very faint mercaptan-type odor. clorpyrifos is not soluble in water. clorpyrifos can cause slight irritation to the eye and skin.

Usage :Insecticide; Acaricide
It's a broad-spectrum organophorus insecticides with contact, stomach poisoning and suffocating. the residue period is not only on the leaves, but in soil, then it has good effect to pets under ground. it can be used for cotton, apple, orange, rice and sugarcane etc.

Air & Water Reactions
insoluble in water. clorpyrifos reacts with water and most reactive hydrogen compounds. the rate of hydrolysis in water increases with ph, with temperature and with the presence of copper and possibly other metals that can form chelates.

Reactivity Profile
Clorpyrifos is sensitive to heat and is decomposed by moisture. clorpyrifos is hydrolyzed by strong alkalis. clorpyrifos is corrosive to copper and brass. clorpyrifos is also corrosive to copper alloys. clorpyrifos reacts with water and most reactive hydrogen compounds. the rate of hydrolysis in water increases with ph, with temperature and with the presence of copper and possibly other metals that can form chelates.

Fire Hazard
combustible material: may burn but does not ignite readily. containers may explode when heated. runoff may pollute waterways. substance may be transported in a molten form.
