2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C 6 H 3 Cl 3 O.It has been used as a fungicide and herbicide. [2] Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly ...
2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants. It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid. It was widely used in the agricultural industry until being phased out, starting ...
2,4,6-Trichlorophenol, also known as TCP, phenaclor, Dowicide 2S, Dowcide 2S, omal, is a chlorinated phenol that has been used as a fungicide, herbicide, insecticide, antiseptic, [3] defoliant, and glue preservative. [4] It is a clear to yellowish crystalline solid with a strong, phenolic odor.
The duration of the SPC can, however, be extended to 5.5 years when the SPC relates to a human medicinal product for which data from clinical trials conducted in accordance with an agreed Paediatric Investigation Plan (PIP) have been submitted (as set out in Article 36 of Regulation (EC) No 1901/2006 [2]).
The World Health Organization (WHO) names four toxicity classes: . Class I – a: extremely hazardous; Class I – b: highly hazardous; Class II: moderately hazardous; Class III: slightly hazardous
The vapor pressure function according to Antoine is obtained as log 10 (P/1 bar) = A − B/(T + C) (P in bar, T in K) with A = 5.44591, B = 1767.766 K and C = −44.888 K in a temperature range from 291 K to 358 K. [2] Below the melting point at −4.5 °C, [12] The 1 H NMR in CDCl 3 shows a singlet at δ=0.14 ppm.
Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as antiseptic/disinfectant.It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers.
The Dow Chemical Company also developed Chlorpyrifos methyl in 1966, which had a lower acute toxicity (WHO class III), but this appears to be no longer in commercial use. The molecule is similar to Chlorpyrifos ethyl, but with a O,O dimethyl chain.
