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 ...
Agent Orange, a defoliant used by the British in the Malayan Emergency and the U.S. in the Vietnam War, was equal parts 2,4,5-T and 2,4-D (2,4-dichlorophenoxyacetic acid). 2,4,5-T itself is toxic with a NOAEL of 3 mg/kg/day and a LOAEL of 10 mg/kg/day. [3] Agent Pink contained 100% 2,4,5-T (dioxin contaminates included). Additionally, the ...
Bis[2,4,5-trichloro-6-(pentyloxycarbonyl)phenyl]oxalate (also known as bis(2,4,5-trichloro-6-carbopentoxyphenyl) oxalate or CPPO) is an organic compound with the formula (C 5 H 11 O 2 CC 6 HCl 3 O) 2 C 2 O 2. A white solid, it is classified as a diester of oxalic acid. It is an active ingredient for the chemiluminescence in glowsticks. [1]
Trichlorophenols are produced by electrophilic halogenation of phenol with chlorine. [1] Different isomers of trichlorophenol exist according to which ring positions on the phenol contain chlorine atoms. 2,4,6-Trichlorophenol, for example, has two chlorine atoms in the ortho positions and one chlorine atom in the para position.
Rauhut and co-workers have reported that the intermediate responsible for providing the energy of excitation is 1,2-dioxetanedione. [1] [4] The peroxyoxalate reaction is able to excite many different compounds, having emissions spanning the visible and infrared regions of the spectrum, [4] [5] and the reaction can supply up to 440 kJ mol-1 ...
TCPO, or bis(2,4,6-trichlorophenyl) oxalate, is a chemical used in some types of glow sticks and is a key chemical in many chemiluminescent reactions. TCPO is classified as damaging to human organs and toxic if inhaled with an inhalable toxicity of 3.02 mg/L and oral toxicity LD50 of 820 mg/kg (rat).
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.
Fenoprop, also called 2,4,5-TP, is the organic compound 2-(2,4,5-trichlorophenoxy)propionic acid. [2] It is a phenoxy herbicide and a plant growth regulator , an analog of 2,4,5-T in which the latter's acetic acid sidechain is replaced with a propionate group (with an extra CH 3 ).
