[overview]
propargyl, chemical name 2-propynyl-(r)-2-[4-(5-chloro-3-fluoro-2-pyridyloxy)phenoxy]propionate, is an aryloxygen phenoxypropionic acid herbicides can effectively inhibit the biosynthesis of esters into acetyl-assisted a hydroxylase inhibitors. they are mainly used to control wild oats, wheatgrass, oats, ryegrass, common bluegrass, setaria, etc.
[physical and chemical properties]
propargyl is an odorless crystal with a melting point of 59.3°c and a vapor pressure of 5.3μpa (20°c). the solubility in water at 20°c is 2.5 mg/l, and it is soluble in most organic solutions. it is relatively stable in acidic media at 50°c and easily hydrolyzed in alkaline media.
