Product Information

• Name: 2,4,5-Trichlorophenoxyacetic acid
• Synonyms: 2,4,5-T
• Brand: Biosynth
• Description: 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) is a herbicide that inhibits the growth of plants by inhibiting photosynthesis. It can be found in the environment as a contaminant of manufactured items such as vinyl chloride and polyurethane. 2,4,5-T is also used to produce dioxin and polychlorinated biphenyls (PCBs). The mechanism of toxicity involves inhibition of the activity of an enzyme called acetolactate synthase (ALS), which is responsible for synthesizing an important amino acid called L-alanine. ALS inhibitors are toxic to animals because they inhibit the formation of L-alanine and disrupt cellular energy production. In CD-1 mice, 2,4,5-T has been shown to have an inhibitory dose at 1 mg/kg body weight with long-term toxicity at doses up to 5 mg/kg body weight. 2,4,5
