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 ...
Tetramethyl acetyloctahydronaphthalenes (International Nomenclature for Cosmetic Ingredients name) (1-(1,2,3,4,5,6,7,8-ottaidro-2,3,8,8,-tetrametil-2-naftil)etan-1-one) is a synthetic ketone fragrance also known as OTNE (octahydrotetramethyl acetophenone) and by other commercial trade names such as: Iso E Super, Iso Gamma Super, Anthamber, Amber Fleur, Boisvelone, Iso Ambois, Amberlan, Iso ...
It was a mixture of 2,4,5-T and 2,4-D. The 2,4,5-T used was contaminated with 2,3,7,8-tetrachlorodibenzodioxin (TCDD), an extremely toxic dioxin compound . During the Vietnam war, between 1962 and 1971, the United States military sprayed 20,000,000 U.S. gallons (76,000,000 L) of chemical herbicides and defoliants in Vietnam, eastern Laos and ...
In the formation of silicon carbide, carbosilanes, such as 1,3,5,7-tetramethyl-1,3,5,7-tetrasilaadamantane, are observed as intermediates. Uses in NMR spectroscopy. Tetramethylsilane is the accepted internal standard for calibrating chemical shift for 1 H, 13 C and 29 Si NMR spectroscopy in organic solvents (where TMS is soluble).
2,2,5,5-tetramethyltetrahydrofuran (TMTHF) or 2,2,5,5-tetramethyloxolane (TMO) is a heterocyclic compound with the formula C. 8H. 16O, or (CH 3) 2 (C (CH 2) 2 OC) (CH 3) 2. It can be seen as derivative of tetrahydrofuran (oxolane) with four methyl groups replacing four hydrogen atoms on each of the carbon atoms in the ring that are adjacent to ...

WASHINGTON (Reuters) -Research animal breeder Envigo pleaded guilty in Virginia on Monday to federal animal welfare and environmental crimes, resolving a two-year U.S. Justice Department probe ...
Tetramethylbenzene. The tetramethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with four methyl groups (–CH 3) as a substituent. [1] Through their different arrangement, they form three structural isomers with the molecular formula C 10 H 14.
