CAS NO.: 74223-64-6
Molecular Formula: C14H15N5O6S
Molecular Weight: 381.36
Melting point: 158 ºC
Property: Pure product is colorless crystal (industrial product is off white solid,with ester odor). Melting point 158C, Vapour pressure 3.3×10-7mPa (25C) KowlogP=1.74 (PH=7). Density1.47. Solubility (25C) in water 2.79g/L (PH7), xylene 0.58g/L, ethanol 2.3g/L, methanol7.3g/L, acetone 36g/L, dichloromethane 121g/L.
Specification:
Metsulfuron-methyl 95% TC;
Metsulfuron-methyl 20%,60% WDG;
Metsulfuron-methyl 20% WP.
Uses: Selective systemic herbicide absorbed through the roots and foliage, with rapid translocation both acropetally and basipetally. Susceptible plants cease growth almost immediately after post-emergence treatment, and are killed in 7-21 days. Surfactants increase the activity of metsulfuron-methyl on certain broad-leaved weeds. Metsulfuron-methyl controls a wide range of annual and perennial broad-leaved weeds in wheat, barley, rice and oats, by either pre- or post-emergence application, at 4-7.5 g/ha post-emergence.
