Aug 29, 2024 · SUMMARY. 2,4,5-trichlorophenoxyacetic acid is an obsolete herbicide that was used mainly on non-cropped areas. It is moderately soluble in water, has low volatility and tends to be persistent in soil systems. 2,4,5-trichlorophenoxyacetic acid has a high potential for leaching to groundwater. Limited data is available regarding its toxicity to ...
2,4,5-T (2,4,5-trichlorophenoxyacetic acid). CAS number 93-76-5. A post-emergence herbicide used for the control of shrubs and trees. The acute oral LD 50 is 300 mg/kg in rats and 100 mg/kg in dogs. There is no evidence of carcinogenicity in long-term chronic studies in rats.
A related compound of historical interest is 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), which has been withdrawn from use because of concerns that arose from contamination of some formulations with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). TCDD can be derived from the reaction of two molecules of 2,4,5-trichlorophenol during the synthesis of 2,4,5-T.
One of the toxic symptoms of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) is reduction in metabolic rate and subsequent growth retardation. Acetylcholine (ACh) serves as an essential growth factor to facilitate amino acid transport and to promote fetal growth. Hydatidiform mole lacks the capacity for …
