Chemical Name:
4-Amino-6-tert-butyl-3-(methylthio)-1,2,4-triazin-5(4H)-one
CAS NO.:
21087-64-9
Molecular Formula:

C8H14N4OS

Molecular Weight:
214.32
Structure Formula:

Formulation:
95%TC/70%WP/70%WDG
Toxicity:
Acute toxicity: Metribuzin is slightly toxic via the oral route, with reported oral LD50 values of 1090 to 2300 mg/kg in rats, 700 mg/kg in mice and 245 to 274 mg/kg in guinea pigs [6,15]. It is practically nontoxic dermally, with a dermal LD50 of 20,000 mg/kg in rabbits [6,15]. The 4-hour inhalation LC50 for metribuzin in rats is greater than 0.65 mg/L, indicating moderate toxicity via the inhalation route [15]. Metribuzin has been shown not to irritate the skin or eyes of rats, rabbits, guinea pigs, or human volunteers [15,32]. Effects of high acute exposure in metribuzin poisoned rats included narcosis (stupor) and labored breathing. Deaths occurred within 24 hours, and survivors recovered slowly without permanent effects [33]. In single high dose studies, metribuzin appears to depress the central nervous system. Other studies indicate that the target organs of metribuzin are the thyroid gland and the liver.
